I found a local store in my area that has several new ones. If you PM me with how much you are willing to pay each I might be willing to go get as many as you need.
Word on the "street" is that they are only going to go up in value as the new Smash Bros. gets closer to release.
One of my friends is in the same boat as you as he had three that he pawned with his gamecube about two years ago. He barely got more than what one new wavebird is selling on eBay at this time.
