No. Only one Fusion Rev. 4 exists. Either its Holy Creator @Ashen has it and is probably not looking to sell, or He has already sold it.
It's currently being sent around the country being upgraded to a Wii portable by various high ranking members of the portablizing community so I'm not sure when I'd even be willing to sell it but sure!
I mean it's kind of like the neanderthals vs. humans; Wii is superior in every way so can you blame us?
i saw that he made molds for casting case I think you should also make mold and sell them it will help many newbies or get it scanned and 3d print
