I can relate to this, well nearly. Thought about selling my D-50 and PG1000 which I've had for years, believe me, it was close when cash was tight but, it's brought me so much inspiration, enjoyment and happiness, and getting a replacement further down the years was just too much to bear. I have an affinity with it, I just can't part with it, I'd sell the wife first!...Commiserations dude, I feel for you in a synthpathetic way.
