do yourself a favor. buy a 686 pre-lock. i had a taurus tracker 627 once. worst revolver i ever owned. if you want a cheaper revolver than a 686 consider a ruger gp100
+1. I own about 20 assorted guns from various makers. The only gun that I have ever had problems with was a Taurus M85. Do yourself a favor, while the price is attractive, Taurus is just too hit or miss to spend the money on.
If the 686 is too pricey, the Ruger GP 100 is a great choice. Cheaper than the 686, more expensive than the Taurus but worth every penny.
