Best of luck to you, and sorry it came to this. After the insurance pays their portion, the hospital may be willing to negotiate down your remaining balance. The facility will be the majority of the total, excluding any implants you're having put in, so if they were willing it could at least take out SOME of the sting. I hope somebody buys your KC and knocks this out in one fell swoop, partly so you get to keep all your cool stuff but also partly so I don't see a boxed synthesizer for sale that I can't buy.
