Does anybody know of a place where I can purchase one of these? The spindle finally gave out on my brothers Gamecube and it appears to be some sort of proprietary deal, so the spindle in an old, broken CD player I had handy won't work.

Looks like the only way I can get one via eBay at the moment is by purchasing the complete drive assembly, which would actually cost more than buying an entire bare Gamecube console via eBay or ShopGoodwill. If somebody has a dead Gamecube lying around and can spare the spindle off it for a few bucks or trade or whatever, I'd be forever grateful.
