It seems pretty obvious that most operators would prefer a clear faced electronic vendor, but there are still major issues to address. And the frustrating thing is that these issues have been known for some time and the basic two people making them don't seem to be able to address them. Fix them and you will sell more of them. Chadpalmer was right on about the display on the IVS/GinSan unit. It is only readable in low light conditions. On sunny days, or heaven forbid in direct sunlight, it's useless. (BTW, chad, are you the Palmer from Bonita Springs?) IVS should come out with a daylight readable one and offer it as a retrofit. Look at the numbers on these vendors. If you want to vend electronically with the drop shelf vendors, you will spend many many thousands more by using drop shelves rather than one of these.
