If you don't sell it, then why not take it apart and salvage the useful bits and pieces? At a minimum it looks like it's got a rotary encoder, a potentiometer, a couple of banana jacks, a 40x2 LCD, a power switch, a BNC connector, and a phone jack. I'd expect there to be stuff inside that's probably useful too, like a transformer, voltage regulators, maybe a SMPS controller, and who knows what else.
And if you do take it apart to salvage parts, then you should take teardown photos while you do it and then post an article on here about the teardown, because it might be quite interesting to see what it's got inside of it.
