Yeah, in good condition it usually seems to go for around $75-$100 it seems - I got mine in mint condition for much cheaper though, but I guess putting that weird mousepad thing in the box causes it to bend all sorts of funny ways cuz there's no real easy way to fold it in there -- still haven't gotten the 2nd one, but that seems to go for around ~$35 on Ebay regularly, so I'll pick it up eventually. I'll keep my eye out for you though Jorge!
Also, now that I've got my image hosting account back, and will be moving many of my games etc. on Saturday again, I'll upload some photos and spruce up this thread a bit!
