Ebay is a great way to advertise and get the word out. Put a listing for an individual copy on there, in several catergories. Put one under 'racing equipment' or similar in ebay motors...I don't know the exact name of the catergory... and maybe another catergory.

Bottom line is that it's very cheap, and with the hit counter you'll be able to see how many people you reached. I'd imagine it would be only a few dollars to reach several hundred people over the course of 7 days. And you might make a sell. You can put a link to your personal site in your listing.

I bought a Powder Coating oven from a guy who did this several years ago. He didn't expect anyone to bid on it via ebay, but he got more than enough orders from people contacting him looking for info, myself included.

Good luck.
