Scott Sherbine at Proficient Billiards does excellent work. I have had many cues refinished by him, to include some higher end cues...always quick, reasonable and top quality.
Ryan (RAT Cues) does great work, also. I have had nothing but great work from him, also.
Mike Webb does a great refinish and leather wrap.
Personally, I now use Cory Barnhart exclusively for refinishes and leather/exotic wraps. No one has better attention to detail than Cory.
Simply said, there are a lot of great cue refinishers/builders out there.
