I went back and looked. I paid $725.00 for the Pre-lock that I bought. Also just looked on GB. There wasn't anything listed for less than about a grand. I don't know if prices are cyclic, or that I just got in at the right time.
Also, both my 629 and 686 are "3T's". Both have nice triggers, but the 686's trigger is a little bit lighter and it's silky.
