To echo what has been said already, it really depends on you and what you like.
I have a C&R, so I have a lot of surplus guns. I love the "feel" of the history, and the heft of an older rifle. As I like to say, 'from a time when an unloaded rifle was still a fairly decent weapon.' You can run across good deals and find a really good shooting rifle for a lot less than a new one (of course, depending on what you buy).
That being said, I also have some newer rifles, purchased new, that I really like. Many of which were not terribly expensive (both Savage and CZ make some good rifles). Of course, there are always exceptions to the rule, and for any given brand someone will have had a bad experience.
Mostly, if you get a rifle that is in decent shape, use good ammo, and a good scope (if you use a scope), the results you get are primarily dependent on your ability to shoot.
