There does seem a rash of these Radio Shack Pro197 scanners up on eBay at the moment and this one still has a way to go before auction end with only a few bids at the time of writing.
Judging by the quality pictures posted by the seller this model looks in good condition with all the bits and pieces you would expect (with the exception of a paper manual, although this is very easy to find online).
A good read of the user manual will bring you up to speed on getting the most out of the Pro197 and if your used to operating the more recent scanners (with their complexity), you’ll find this Radio Shack model a piece of cake.
Life is made simpler with an included programming cable that allows you to alter the PRO197 via a computer (if you’ve ever tried to do a huge manual memory program, you’ll know what a benefit computer cables are!)
