ScottR and Bruce immediately come to mind as well as Sherwin Chang, Erik Lee, Hunter, Ross, Matthew Staton, Jazz, jazznpool, mattntorrence....pretty much safe to say I have been fortunate enough to have more good experiences than bad.
As far as cuemakers, I would recommend Bill Schick and Arnot Wadsworth.
Whitten is the best casemaker I have dealt with personally...but I love my Porpers.
As far as repairs and custom mods, I have done business with Bill Cody, Joe Ezell, and Greg Colvert. All straight up good guys.
Just remember, if it quacks like a duck and walks like a duck...it's probably a DUCK!
