Well, desireable doesn't mean much if you can't find someone to service it or if you can, it exceeds the price you paid. You can try a place like Audiogon to sell it and to get an idea of potential prices maybe try AudioKarma. As to it being in excellent condition, without a professional checkup, you might be right on or it may be wishful thinking. Myself, I'd look to see if I could fix the light myself and I'd probably just hold on to it.
"I've found that when you want to know the truth about someone that someone is probably the last person you should ask." - Gregory House
