Konami Hyperbeam SNES Wireless Controllers

[GameGavel]

Wow! Just scored one of these at the swap meet last week for $5. Appears to have never been used. Just hooked it up and it is really a great wireless controller. Surprisingly well made, too. And nothing looks cooler than having a satellite dish sitting near your TV :) Anyone else have one? I couldn't find to much info on these around the net and no sales history on Ebay or anywhere else. Is it harder to find?
