Ebay Link with Pictures...

Kaze Aerocraft also made one, but it appears to be out of production I think.

ZEEK made one, but I can't even find somewhere that claims to sell a replica of it, so I guess good luck there.

I did my best, it's a few places to look I suppose, but alot of what you're gonna find is gonna be knock-offs and stuff. Might still work for you, might not. :-\
