I got a hold of DDR EXTREME 2 @ K-Mart for 10 bucks but I'm still looking for the others. I used to own them and there's something I like about all of them, inculding EXTREME. You know what though, the trade in thing just might be what I need to do.
In case anyone wants to point me to a sweet deal though, I'm still looking for MAX, MAX2, and EXTREME.
