Radiocrap has some odds and ends you can't find anywhere else, but in general they sell crap. I wouldn't even buy cables from them because they sell cheap everything. But finding stuff like transistors, rca plug adapter, or a hobbyist that wants to make a cheap radio from scratch their ok. Their vacuum tubes are not the best but they work especially for lower end tube electronics; I have a old 50's era Zenith am radio and have no problem using Radio Shack tubes for it (if they still have them for this radio, I bought the last set over 20 years ago), but I wouldn't use RS tubes for my McIntosh 275.
