You may want to check out the link posted below. This is where Pete is getting the nice planes from. They even offer them in various quantities including just "one" plane purchase according to the website. Just click on the multiple pictures listed for a specific plane and look at the details on minimum order required. Some offer just one to be purchased. If I had the balls and money I would give it a try. It may take a while to get them in the mail. They are in China.
