A while ago, I was given some old drums that a friend of the family found under a house. They are yellow Pearl drums, "Pearl World Series" rock/standard sizes (I think). 12"+13" rack toms, 16" floor tom, 22" bass. The rack toms have both heads and rings, the floor only has the top head and ring (correct word?), and the kick has only the beater ring, and no heads. There is no snare. The floor tom has legs but no bottom ring, the rack toms don't have mounting arms, and the kick doesn't have the back side ring or tension lugs or claws, etc (it has all the hardware for the beater side, though). There are no stands. I have no idea what these are worth. I went to guitar center because my friend has a discount there, and found out that it would cost about $300 to get everything I would need to have a functional set, and I don't have that much right now. I'm having a bass built, and I really need the money for that, even though I really would like a drumkit of my own. Any idea what these are worth? They are in under-a-house condition, but I have the time to polish them up and do what I can to make them nice. Any help would be greatly appreciated.
