CREDIT ARRANGEMENT [Abstract]
CREDIT ARRANGEMENT	Note 5, Credit Arrangement: In March 2016 we entered into the First Amendment to Amended and Restated Credit Agreement (the "Credit Agreement") with a bank.  The Credit Agreement amends our revolving credit facility to increase the aggregate commitments from $50.0 million to $60.0 million, extend the maturity date to March 31, 2021 from September 1, 2016, lower the commitment fees on unused amounts, reduce the applicable margin for interest rates on borrowings, modify the borrowing base calculation, and change the collateral reporting requirements.  We have not had any borrowings under the revolving credit facility since its origination in 2008. The $60.0 million revolving credit facility is secured by inventory, accounts receivable, cash and certain other personal property.  Our Credit Agreement includes negative covenants that limit our ability to, among other things (a) incur, assume or permit to exist additional indebtedness or guarantees; (b) incur liens and engage in sale leaseback transactions or real estate sales in excess of $100.0 million; (c) pay dividends or redeem or repurchase capital stock; (d) engage in certain transactions with affiliates; and (e) alter the business that the Company conducts. Availability fluctuates under a borrowing base calculation and is reduced by outstanding letters of credit.  The borrowing base was $53.4 million and there were no outstanding letters of credit at December 31, 2017.  Amounts available are based on the lesser of the borrowing base or the $60.0 million line amount and reduced by $6.0 million since a fixed charge coverage ratio test was not met for the immediately preceding twelve months, resulting in a net availability of $47.4 million.  There were no borrowed amounts outstanding under the Credit Agreement at December 31, 2017.
