I bought my PRO-2010 at a street sale for only 2 euros. And 2 euros is about it's maximum value, I think. The volume knob makes a scratching noise when turned, that will need some work. Beyond that, it seems in decent order considering it's age.
The scanner has a nice vacuum fluorescent display, blue. Direct frequency entry is handy. Programming is a bit clumsy, like all Realistic scanners I've seen so far.
All in all, it should function well as standby receiver, or with additional discriminator output, as text-message receiver.
