From what I've read, Paul Dayton does phenomenal work and it's all by hand, no CNC and has been doing his inlays this way for years. Another good cuemaker and is very much into promoting the sport of cueing is Pechauer.
I agree with Rad, Paul Drexler, PFD studios, would be a great addition.
I like a lot of the cue makers works of art, but know little about them, except for what I read on this forum or on their sites.
