Don't forget about the SKS! one of the guns most overlooked by serious collectors! Gotta love the poor man's com bloc garand, though, and at about 250-350 depending on local prices, you can still pick up a decent Norinco for relatively cheap. (or a yugo from samco global). Uses the same ammo as the AK's too (7.62x39), so ammo's most likely going to be available in the future with the volume of AK and SKS enthusiasts (whereas something like the K31 ammo, GP11, is a bit more niche)
But I do love my mosins
