Well for a budget, 17" rims are going to be a lot cheaper to get tires onto. Not sure if you want 17s or 18s and are ok with 9" wide all around or if you want staggered or what?
In the end you kind of just have to go with what YOU think is the best looking wheel/tire combo.
Also beware of pre-mounted wheel/tire combos on the various websites. They can be really great and nothing beats just getting the stuff on your doorstep and bolting it on and driving. However, some of the sizings are... off... You have to look at exactly what you are getting and make sure its all kosher. As an example, there is an 05+ wheel/tire combo on AM right now where the front tire is 1/2" taller than the rear and it looks funny. Just gotta watch stuff like that.
