I've seen the same kind of pricing at recent gun shows.
The internal locks and MIM parts never really bothered me but it seems like just about ANY pre-lock J-frame (and K,L,N) have skyrocketed.
I was eyeballing a beautiful .22 kit gun (stainless) until I saw the asking price of $650! Ouch.
Of course, I still see a lot of the SAME guns at some of the same tables year after year.
