I've really only dealt with 4 cue makers and 3 of them have been great.  
Paul Mottey.  Ran into him one year at Sbe while he was shooting in the tourney.  Watched his match, shook his hand & proceeded to tell him how I picked up one of his cues & wondered if he would take it & change the joint for me as I like ivory & not a fan of ss.  He said no problem, was informative & super friendly.
Paul Fanelli.  Was a great man.  So much to say about him, but if you had the pleasure of meeting him, you know how awesome he was.  Loved spending time with him & enjoyed hanging out in his shop.
Steve Dunkel.  Amazing cuemaker.  Great guy, fun to chat with, has a ton of stories & very knowledgeable.  Always bothering him to do work for me & he accepts my addiction & helps me out.  Will continue to support him for a long time.
