Thanks for the input.
I have decided on 17's, with a 40 or 45 profile tire.
These will do nicely:

Of course, another eBay store is selling them brand new for almost 100$ cheaper.

Oh, and my car is an 01 Sedan LX. I want it to look sporty but conservative as well. The next step is to put some new springs, prefferably a 2" drop, on factory struts (I'm married with kids, $ has a tendency to be tight. I don't think there is much need for high end performance struts when I am the only one who is ever in my car, and I only go to and from work.)
