I put down "Condition" for my vote. I think it gets overlooked too often in favor of 'rarity' and country/arsenal (which is just rarity prettied up for the Izhevsk snobs). What may be über rare to one person might be just another new condition Yugo to another.
Condition, BAH!!! OVER RATED!!!
Old, used, beat to death, mismatched, sloppy tolerances, dirt in the action is what "Communist military surplus" is about, thats whats sexy, especially when you pick one of these Commie made turds up for the first time, rack a stripper clip in them and dong the gong at 200yards. If one wants new, shiny, purdy, slick rifle, they roll off assembly lines all day, everyday, for roughly the same cost and are even higher quality than these street and jungle beaters are, but, these have no life, no dirty, dark trench secrets, no blood on their hands, no soul.
