Stock wheels are always at a premium whether you are buying them new or buying them used. I did sell my old 14" miata wheels pretty cheap, and then eventually the 17" wheels from my MSM also went pretty cheap. Many/most big cities have at least one if not a few places that sell used stock and aftermarket wheels. The prices may not be good, but they will be much better than the price for a new part from the dealer.

I think some inexpensive after markets are the way to go unless you can wait for some good take-offs. You may want to watch Craigslist and any local car clubs for cars that have wheels that fit that you might want.
