Well there usually are a bunch of lousy beat up ones, but I grab the gems when I see them. I bought one for $6 today that sells for $140-$200 used!

I've been teaching myself the golf club category and I'm finding the same thing there: Most of them are beat to hell and back. :-)

Some clubs are sneaky expensive so that's a good niche. I've found some gems before in stores and on the curbs. The only catch is that shipping can be a little expensive. All it takes is one good putter or driver and the digging through the crap is worth it.
