what do I look for when buying a radio project?

[Donny]

Now that my philco is done I'm looking for more! I hit ebay and noticed lots of cheap radios,somehow most of these are stated as working (I doubt it) I went ahead a won a teletone wood radio (dead the way I like em) but now I'm thinking maybe off brands are bad! parts and info might be hard to find. So zenith?philco? 40s?50s?60? I've just been shopping for cool looking cheapys.
