no one has mentioned this, so I will, my personal favorite is the Mosin Nagant M44, there under $100 brand spankin new (70 years old, but never fired, all matching parts, got mine on gunbroker.com) There accurate as heck, I buy the surplus ammo at shows for cheep, and they are really really easy to modify, I'm gettin mine drilled and tapped for a scope in a few weeks, and I cut the end off of it to remove the bayonette. it's a good solid gun with few moving parts, so you can never jam or go wrong with this one.
Just a thought
