There's a member here named Rodney who's in your neck of the woods, 65Baja. He knows of a source for reconditioned drums in Sac that sells them for a reasonable price - if you're not into going the scrap metal dealer route, that is. Maybe shoot him a PM and ask him for the source? I know he posted that info here in this thread, but buggered if I can remember what page it's on.
