My favorite affordable old rifle is my Swiss K31. The quality is very high and it's different, I like things that are oddballs.
I used to hate Mosin's, mine shot 4-5" groups with milsurp ammo and at the time I was wishing I had bought something else. A few years went by and I bought dies, brass, and .311 174gr SMK's. Now it's a sub 2" rifle with me and the old irons. It functions perfectly, the bolt is pretty smooth, it balances well, so I changed my mind and find myself using it more than some of my other old rifles.
I don't own one but I'd like to get a Krag, IMO the smoothest old turn bolt around.
