text: The Company has a revolving credit facility (“Credit Facility”) with a regional bank. In December 2001, the Credit Facility arrangement was amended to 
  increase the credit line under the Credit Facility from $18.5 million to $25.0 million. Under the Credit Facility, the Company and certain of its subsidiaries 
  have a line of credit which is secured by substantially all inventory, equipment and accounts receivable of the Company. Interest under the Credit Facility is 
  assessed at 30-day, 60-day or 90-day LIBOR, as selected by the Company, plus one percent (2.17 percent at December 31, 2003) and is payable monthly. 
  At December 31, 2003, and 2002, $4.3 million and $10.3 million, respectively, was outstanding under the line of credit. The Credit Facility expires 
  November 12, 2006, and may be extended under certain circumstances. At any time during the term, the Company may convert any or all outstanding 
  amounts under the Credit Facility to a term loan with a maturity of two years. The Company’s ability to borrow funds under the Credit Facility from time to 
  time is contingent on meeting certain covenants in the loan agreement, the most restrictive of which is the ratio of total debt to earnings before interest, 
  income tax, depreciation and amortization. At December 31, 2003, the Company was in compliance with all financial covenants.
