I found a trade that included a modded Wii and a terabyte of information. It turned out that the hard drives were junk or damaged in shipping though so right now I got the sort end of the stick trading my $900+ in computer parts for $300 of Wii.
To be fair, the guy claims to be re-assembling the information that was on the drives and says that he will get it to me but then again, he doesn't seem to be in much of a rush or even keep me updated... Yea, I'm still hoping for the best but expecting the worst.
