There are a couple now for sale in Florida, listed on eBay. I know they're really far from you, but once the snow gets heavy in Pittsburgh, you might appreciate a road trip to the sun.
There aren't many G101s out there, and you really limit yourself if you will only buy an organ that's fully functional. Maybe someone here can recommend a tech not too far away from you. Or maybe call Retrolinear (located near Philly) and see if they know of someone near you.
(Actually, I think they periodically send out a truck through several states to pick up gear that needs repair. So that may be an option, too.)
