I have a DS phat, and I'm looking for a decent, well-made slot-2 packs that have GBA support. After going through each review, it seems as though the EZFlash IV is the best DS phat slot-2 pack, however, it is a bit pricey ($30.90 USD from DealExtreme). Are there any good slot-2 packs that have GBA support and are not as expensive?
