S&WIowegan- I paid $2500 for my Galil ARM (7.62) in 2002 which even back then seemed somewhat reasonable. I was 21 so I didn't experience the $600-800 Galil in the 1980s. They 7.62 ARMs seem to be holding steady around $3500 these days.

I also remember a company was mfg AK underdolders with the stocks pinned open.
