they don't have nearly the appeal as most colt revolvers. they are starting to gain interest though and i would buy one if it was excellent shape. your info on them is basically correct. there are fewer of them than a lot of "collector" guns being accumulated. personally, i feel this maybe the time to start buying. after all,earlier sako actions like these are some of the best available. in the .223 caliber i have seen a few over the years,but always had other things to buy. might be an area to study up on.check book of colt firearms by sutherland and wilson as a starting place. good luck. if you can get some pics before you buy,put them up so we can see them. lots of knowledge on this site,not just smiths
