Okay, I've decided I want to try swap out the batteries in some of my original Gameboy games. (Pokemon, Wario Land etc.) I've got a gamebit tool but I don't have a soldering iron. I thought I'd try grab a 15w iron as that's what's recommended for Wii Modding etc. I can't find anywhere that sells them though nearby. DSE only sells either 8w or 25w. I thought about buying a RadioShack one, but they're 110v, not 240v right? I'm about to give up, but I was hoping one of you guys would have some recommendations.
