Jim is good, but expensive. Worth it if you can never seem to get get your boots dialed.
Kelly Timmions has a good rep, but I would stay away. He is not as good as Jim Mates, and is quite expensive as well.
As far as shops go, I am biased, but I would place sturts at the top of the list, Seattle ski does good work, and evo is alright if you just need width or a toe punch.
