Pre lock (preferably P&R) S&W for their fit, finish, feel, accuracy. Shooter grade revolvers are quite a bit less $$$ than new.
Second is Dan Wesson. I only own one, a 4" 15-2 of '72 vintage but I really REALLY like that revolver! The blueing on it is drop dead pretty, trigger is awesome and it's a tack driver. IMO the older DW are a super bang for the buck.
