My Brother in law has a set of 20" Aftermarket wheels for sale. I can get you price on them, they are in good shape. Black centers, and Aluminum rim part. Lugs, and Caps included.
Keep trying Craigslist, I bought a set of factory aluminum rims for my '03, with good studded M+S tires for $375 5 miles from my office. There were quite a few in the PDX area for the '04 and newer models that seemed pretty reasonable.
