I have three, one from each manufacturer. They are definitely fun, I find the Mosin 91/30's to be more accurate but you can knock over a milk jug at 200 yards without much trouble. Some manufacturer/year combinations are difficult to find and command a bit of a premium as far as current collector value goes, if you can locate one built in 1945 you could easily start a bidding war in the EE, I think there's only a handful in the country.
Red rifle supply is slowly winding down, maybe sooner than expected with recent turmoil in the Ukraine. I'd buy sooner than later, at the very least expect prices to start increasing.
