I've added a new service to my list of things I can do. I'm now offering a LED mod for the SNES. $10.00 plus return shipping gets you a new color LED. Right now I have the following colors on hand: Green, Blue, Yellow, and White. No need to send your entire system either. All you have to send is the controller port piece. This will greatly save on shipping costs.
As a reminder, I still do NES, SNES, and N64 cartridge battery replacements, and I still have a lot of XBOX 360 drive belts available.
