      Form 10-Q for the Quarterly Period Ended September 30,

Dear Mr. Driscoll:

		We have limited our review to only your financial
statements and related disclosures and do not intend to expand
our
review to other portions of your document.   If you disagree
with a
comment, we will consider your explanation as to why our comment
is
inapplicable or a revision is unnecessary.  Please be as
detailed
as necessary in your explanation.  In some of our comments, we
may
ask you to provide us with supplemental information so we may
better understand your disclosure.  After reviewing this
information, we may or may not raise additional comments.

	Please understand that the purpose of our review process is
to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your
filing.
We look forward to working with you in these respects.  We
welcome
any questions you may have about our comments or on any other
aspect of our review.  Feel free to call us at the telephone
numbers listed at the end of this letter.

Item 1. Business, page 2

1. We note your disclosure of the three major customers. In
future
filings, please provide the complete financial statement
footnote
disclosure required by paragraph 39 of SFAS No. 131.

2. We note that you have separate businesses in the United
States,
Germany, Canada, and Hong Kong. Your income tax disclosures
suggest
that the German operations are consistently less profitable than
the domestic operations. The disclosures in Note 10 reflect
varying
revenue growth rates. It is not clear how you determined that
there
is only one reportable segment as contemplated by SFAS 131.
Please
provide us with copies of the relevant financial reports
reviewed
by your chief operating decision maker - see paragraph 10 of
SFAS
131.

Results of Operations, page 6

3. In future filings, please expand your discussion of your
results
of operations. Identify the new products that materially
impacted
sales growth. Discuss the economic and competitive factors that
enabled the increase in market share. Discuss the impact of any
product price changes on sales and/or gross margins. Refer to
Release No. 33-8350: Interpretation - Commission Guidance
Regarding
Management`s Discussion and Analysis of Financial Condition and
Results of Operations.

September 30, 2005 Form 10-Q

4. Given the materiality of inventory and receivables to your
financial position and liquidity, please revise MD&A in future
filings to consistently disclose the inventory and receivable
turnover ratios for each period presented. Please explain any
variances. We note that the increases in these asset accounts
appear substantially disproportionate to the corresponding
increases in sales. Further, it is not clear why the third
quarter
inventory build-up is attributed to an "anticipation of future
business" given that fourth quarter sales are traditionally
weaker
due to the seasonality of your business. See Item 303(b)(1) of
Regulation S-K.

5. The disclosure in Note 7 states that the tenant paid all
insurance on the Bridgeport property. In a letter of
supplemental
information, and in future filings, please explain why the
building
damage was not covered by insurance. Disclose also the business
purpose of the arrangement whereby the tenant was given a one
dollar purchase option and was allowed to lease the property for
one dollar per year under the 24 year lease. Given the
immaterial
fair value of the property, it is not clear how any substantive
benefit was gained by the Registrant through this arrangement.
Clarifying disclosure is required given the significant impact
the
loss has on annual operating results and on liquidity.

6. The disclosure in Note 7 states that the $1.5 million loss
provision covers the July 2005 property damage as well as
environmental remediation costs. Given the magnitude of this
charge, please explain in a letter of supplemental information
your
basis for the disclosure contained in Note 2 to the June 30,
2005
10-Q. We may have further comment.

		Please respond to these comments within 10 business
days,
or tell us when you will provide us with a response.  Please
provide us with a supplemental response letter that keys your
responses to our comments and provides any requested
supplemental
information.  Detailed letters greatly facilitate our review.
Please file your supplemental response on EDGAR as a
correspondence
file.  Please understand that we may have additional comments
after
reviewing your responses to our comments.

      We urge all persons who are responsible for the accuracy
and
adequacy of the disclosure in the filings reviewed by the staff
to
be certain that they have provided all information investors
require for an informed decision.  Since the company and its
management are in possession of all facts relating to a
company`s
disclosure, they are responsible for the accuracy and adequacy
of
the disclosures they have made.

	In connection with responding to our comments, please
provide,
in writing, a statement from the company acknowledging that:

* the company is responsible for the adequacy and accuracy of
the
disclosure in the filing;

* staff comments or changes to disclosure in response to staff
comments do not foreclose the Commission from taking any action
with respect to the filing; and

* the company may not assert staff comments as a defense in any
proceeding initiated by the Commission or any person under the
federal securities laws of the United States.

		In addition, please be advised that the Division of
Enforcement has access to all information you provide to the
staff
of the Division of Corporation Finance in our review of your
filing

							Sincerely,
