SP vs DS? Well, the fact that you don't own any GBA games (I'm assuming) pretty much makes it a toss-up. I don't know if a net cost of $20 would be worth playing your old Toasterboy games for a few days. Then again, the DS might go down in cost before the holidays, but since they already have the DS + free SM64DS thing going on, we can't really be sure. I guess I would opt for a DS if you're just going to sell the SP anyway.
