I have bought a couple of cues from Recollection Cues. Tom Watters is honest and easy to deal with.For what it's worth, I would also look at superiorcues.com and recollectioncues.com.
Both tend to maintain a good stock of very nice and desirable cues, from mild to wild representing some of the best builders out there.
I agree with Dave in FL about Chris Nitti. I have one of his cues, and it plays and looks great.
