I've recently returned to using my DS Lite after a few years away, and I have a CycloDS along with an EZ-Flash 3in1. Everything has been working fine until I noticed that my GBA saves were no longer being written to the microSD. Sounds like my 3in1 battery has bitten the dust. Since replacing the battery looks to be a bit of a hassle, I'd rather just but a new one. I'm having difficulty finding a trustworthy online retailer who carries it, however. Many sites have unsecured HTTP checkout pages even if they claim to use SSL encryption. That's a red flag to me. If anyone could vouch for a site that ships 3in1's to the US I'd greatly appreciate it. PS - there's no reason to go with a IV over the 3in1 for the CycloDS, is there?
