Carl: My case is a little different than you asked for, but might help you. I bought a 6" SS 357 Tracker about four years ago. I have shot about 500 max 158 gr deer loads through it and about 2000 moderate 125 gr loads through it. I love it and it has been a great handgun. I have just a few minor complaints with this gun: 1) The orange rectangle PAINTED on the front sight wears off quite soon with shooting and cleaning (with Rem Oil) and I have repainted it on several times. 2) The extractor rod often turns loose after extended shooting and must be retightened (left hand threads). Maybe I have just not tightened it hard enough and or I should try some loc-tite. 3) The ports are not really needed (IMHO) on gun of this size and caliber and just add a lot of noise. Still, this is my favorite 357 and one of the last of my eight handguns I would consider giving up.
As far as Taurus service: about six months ago I sent in my PT745 after a few hot handloads (that worked fine in my Kimber 1911) caused some slide problems. I had it back in 3 weeks working great free of charge (dealer paid shipping to Taurus).
I have no problem buying a Taurus. As with any purchase, examine the gun carefully, preferably buy from a reliable dealer who can help you out should you have a problem.
