Taurus has made some real improvement in their wheelguns over the last few years. That said, I work in a gun shop, and we see a disproportionate amount of them coming back for service within a few weeks.
Taurus does offer a lifetime warranty, but in reality, it means being without your gun for quite some time. I had one customer who simply gave up after five months, and they wouldn't return his calls. I've had two others who'd rather pay our gunsmith to fix them than wait for Taurus.
Just last weekend, we had a 66 with the cylinder bound up out of the box.
The one time I had to send a gun back to S&W, they paid shipping both ways, I had the gun back in ten days, and they threw night sights on for free "for my trouble."
