I found your product from a posting in the Code Gear news groups -- there were several listed, but this one posting indicated that the programmer was very happy with your product. Those kind of recommendations I take seriously. Also, the price was reasonable for the functionality.

It was very easy to learn and I had an interface developed with a Fujitsu 6130 ADF scanner in just a few hours. Great product!
