I had one of these radios a few years ago and it was probably the nicest radio I have ever had. It is VERY easy to program, has a failsafe available for every channel. It is, also, a very easy radio to convert over to 75 Mhz. Kevin and Jeff like the Futaba 9ZAP, which is an excellent radio with more programming capability than the radio I purchased. They are readily available.
I have only seen one for sale, and it was the transmitter only. It seems as if the ZAP is a radio that does not come up for sale often, but it was a $2,000 radio when it was new!
