I'm looking to purchase a flash card for a DS Lite that will be used by young kids (kindergarden) to play backups of their games. The most important aspect is that it is very simple to use (both the loading of backup roms to the card and selecting/launching games from the DS Lite)... and it must support sleep mode and all that. All the fancy stuff doesn't matter (media playback, etc..). It would probably be nice if it supports DS to DS stuff that any games might use in case the kids want to play with each other. I keep reading that CycloDS is the best but it's also the most expensive. I'm guessing its overkill for the kids needs since they aren't really going to get crazy with features or anything. But if it's the easiest and the most straightforward, then I'll of course consider it. Any feedback (including best place to buy it in the US) would be appreciated.. thanks!
