last time i checked ebay prices are not representative of what things are worth! for example there are ashly sc66s up on ebay for $800!
too bad you don't want to let go of yours... i'd give you $200 for it!
I lucked out and got one on Ebay for $125 when all the other listings were in the $400 range. I don't want to let it go either. Do a saved search on Ebay and cross your fingers!
