I'm going to buy a CycloDS soon, but I'm not sure if I should buy an EZ 3in1 or not. From what I've been able to find, you'd only need it if you want to play GBA ROMs with it. If I don't plan on playing any GBA ROMs, would there be a use for it to me? I don't need to use it for extra memory for the Opera Browser, or a rumble pack or anything, so I'm not sure if I want to spend $20 on it. Also, is realhotstuff.com a fast, reliable place to buy one from?
