There is a local shop that has a bad reputation for being high priced. Maybe on new guns but I've scored some good used deals.
I recently stopped by just to browse, Lo and behold I see a 66-1 2-1/2" for $400. Thank God for credit cards. It had some light pitting under the left side but I was able to remove it.
I've been on a run of K frames. A 64HB, a 64 pencil, a RHKP 10 and this 66-1.
