I got turned onto 'em by a retired engineer here in the DC Metro area. It's tough to beat the prices on some of this old equipment, and the good thing about 99.9% of it is you can still repair it with OTC parts. And, the service and cal manuals have the full schematics and photos of the PC boards to help. And 99% of those manuals are free for the downloading and printing out in dead tree copies.
