Don't buy any revolver you can't check out before you buy.
Search for "check out new revolver" there are many pages describing the process. If lockup is tight, gaps are good, and all cylinders align, the revolver should be good to go. Go through the whole procedure, and check every cylinder.
Taurus' initial quality is historically lower than Smith and Wesson and Ruger. The other 2 have made lemons, too...if you go that way, run the check on them too. However, if you get a good, tight revolver from anyone it should last a good long time. A Taurus that leaves the factory as good, usually stays good.
I have Smith, Ruger, and Taurus in the safe. My favorites all say "Taurus" on them.
