meh, I'd say if you're going to get a nice custom kit get something that has the "natural" feel to it, not the "modern" feel.
Examples would be Cravviotto, Brady, SJC, Unix, noble & cooley, etc.
A couple of the big production companies are starting to create custom lines, so you might want to check out some of those too. The ones I know of are Pearl Masterworks, Sonor SQ2, and Gretsch USA Custom.
I'm thinking of getting a chameleon ash kit from Crush drums. Does anyone have any input on them?
