If you want a custom kit built for you, rather then going to one of the larger companies (ie DW, Ayotte, etc), I strongly suggest you check out ghostnote.net
There's a heap of people there who put the big guys to shame; Franky (Unix) is one worth noting, as is Bill Caldwell (C&C), Josh (JMS drums), Mikka (Phi), Kurt (Hillbilly... the best paint finishes on the planet), and a heap of others who's work never ceases to amaze me. You can get anything from people there; stave, segment, acrylic, steel, magnesium, exotic woods, custom airbrushed paint jobs, albalone finishes, custom printed wraps... pretty much everything is the best in the biz. Exactly the reason Pearl keeps steeling their ideas and trying to patent them...
