Tower of R2-D2s at The Sharper Image
This R2 unit was actually launched back in 2002 but it sold out quickly and Hasbro had supply problems, so it was very difficult to get a hold of one of these droids back then, unless you wanted to scour eBay and pay over $200. It was re-launched in September 2006 and has not suffered from the same supply problems, although there are times when these are difficult to find. There aren't sold everywhere. The most popular place to get them is at The Sharper Image, which is where TechRepublic found one.
