... I would prefer a new kit. So I've narrowed my search down to the Yamaha Stage Customs, PDP concepts, and Tama Silverstars...
MyDentity kits sure look nice, but I rather spend that kind of money on a used high end kit...
.... There's about 3 Guitar Centers and several other privately owned music shops I can visit locally...
Reading through this thread, it sounds like you're in the beginning stages of deciding what you want.
Visit all the local stores, look at, and if possible, try out, as many kits as you can.
Research the kits you're interested in on the manufacturer's sites.
That should help you sort it out more. I don't think you'd go wrong with any of the 3 sets you're considering in the first post.
Buying used will get you more drum for the money, but will entail more work, and more risk.
Good luck with your search.
