$1k isn't a lot to spend on a firearm. I've got a few that are worth more than that. But at the moment I'd like to pick up a better bolt-action for hunting. I think I could get a low-end R700 and some good Nikon glass for under a grand, though I could easily spend over 1k on that combo as well. If it's just $1k for the gun, then I could get a better R700 and even better glass! I'd also like to try a good Leupold scope, though that's been way out of my price range so far.
Oh, but staying on the thread topic, if I could only own one gun and could spend a grand on it, I'd go with a Sig 220 or 226.
