Drop me an e-mail and I can give you the name of a 'smith in Mass. that's top notch with Dan Wessons. He's done a couple for me that rival the 715 Daniel B. personally hand tuned for me.
Another suggestion, check for any IHMSA matches in your area. If you go, I'll guarantee there will be some mighty fine DW's there. I'm sure any of the competitors will tell you the name(s) of the people that worked on the action for them.
