check local area dealers and even craigslist has some that are cheap and in relative new condition. Just gotta look around. I'd say check out your local craigslist for anything you may like and check if you got a 4lug wheel. I know some people that have gotten pretty new rims in damn near perfect condition and semi wore in tires for 400. Just gotta look around.
Go to tirerack.com. They have very decent priced wheels and you can use their "show it on car" to get an idea of how their wheels look on your car. I've bought wheels and tires from them -- they are super!
