Custom sight work for J frame

[PeacefulWarrior]

I am thinking a having a tritium "big dot" front sight installed on a J frame Smith and am looking for a good gunsmith/shop to do the work any suggestions?
Not too long ago I saw an ad for a shop that specialized in this but I can't remember who it was. Thanks

I've had sight work done by http://www.cylinder-slide.com with good success.

www.alphaprecisioninc.com does a great job of this but you will be without your pistol for awhile.
