I like StewMac for certain neat little tools,
and branded stuff like Switchcraft parts. They will skimp on certain things, they sold the bootleg Bill Lawrence pickups for years and they sell Fully-Finished Guitar Bodies with "spectacular quilted maple tops!" for only $195! Try and buy that at Warmoth....
I'm not a big believer in the idea that I need Jason Lollar or Greg Kinman to custom wind me my own personalized $350 pickups to play "Suzie-Q" better on, but pickups (and tuning pegs) are about the last place I'd try to skimp out.
