I saw that the EZ3 4Gbit only costs $55 over at winsunx (http://www.winsunx.com/list.php?mod=630), and wondered if it's a good buy? From the gbatemp review, it seems really good, unless the 4Gbit version is crappier than the 1Gbit one. I'm planning to use it with my Nintendo DS, but only for GBA games. I already have a SuperCard SD, which works fine for NDS and emulators, but not so fine with GBA games. So what do you think? Is it a bad choice? 512MB should be enough for only GBA stuff. Am I missing something about the price? Is it like the M3, a cheaper chinese version and a more expensive one for the rest of the world? I know that shipping is ~$20, but it's still cheap.
