I'm a former IT and cell phone repair expert with 12+ years of professional experience, and I would be thrilled to install a Picoboot IPL kit in your (otherwise-working) Gamecube for a flat fee of just $85. I operate out of southern Westchester NY and can easily travel to the surrounding area.
This price includes service, the Picoboot, a GC2SD card adapter and any help you need to get up and running.
Contact me for more info, or if your hardware needs further repair!
