Not a GREAT price, but then, it's sort of a regional thing. Around here used Smiths are outrageous and used Tauri are bargains. I picked up a blued 3" M66 (M65 with adjustable sights) that had a timing problem for $180 at a recent show. I took the side plate off and found a kinked cylinder pawl spring and fixed it and it's perfect now.
I got a 4" M66 new lockwork with a VERY smooth DA trigger for $197 at a show about 5 years ago. That one is like new, nickel finish. Both guns are extremely accurate with either .38 or .357 magnum and I'm a sucker for accuracy. I've got through a Ruger Security Six, a Smith M19, and a Rossi M971 looking for a .357 that shot .38 half way decent. The Rossi wasn't bad, the Smith and the Security Six were worse. Maybe I got lucky, but the two Taurus M66s are tack drivers with good .357 and my .38 Wadcutters. I'm a happy camper now.
The Taurus is a medium frame gun like the Smith M19 I had. With the way I shoot, mostly .38s in my .357s, they'll last a good lifetime, anyway. I wouldn't worry about wearing the thing out. The K frames that gave the bad reputations were heavily used police training guns. I'll take the somewhat less strength of the K frame for the light weight and added comfort while carrying over the L frame or GP100. Old Ruger Security Sixes are strong guns, but the one I had was pretty severe in recoil shooting hot stuff. My Tauri, my Smith, and my Rossi all were easier on the hand, climbed less on recoil. I really never quite figured out why that Security Six was so rough to shoot. I got used to it, but the Taurus is much easier to control. You could use the Security Six for a hammer and never hurt it, though, one rugged revolver. But, I can't advise against that Taurus based on my experience with two of 'em so far, danged accurate, good shooting K frame sized guns.
Check and see if the gun is the later model lockwork with the transfer bar. My nickeled four inch has that lockwork and it's a bit smoother than my older one with the hammer block lockwork. It rivals any Smith for smooth DA trigger. I can't really say that about the older one. Ain't that it's THAT bad, just ain't as smooth. If the gun has the transfer bar lockwork, it's a decent deal I'd say. If it's the older lockwork, it's a bit overpriced IMHO even accounting for regional differences. Still a good gun, though, and wouldn't be THAT overpriced.
