ebay will give you a value, if you use a reserve you won't have to sell for what you consider too low.. listing a vehicle is flat rate on ebay (was $65. for a motorcycle) and you get that refunded if it doesn't sell. there is not a percentage charge if sold, just the listing fee.
the idea of implanting a a Nevada 750 would be cool, or could you fit all the body work to a newer SB like the Stone?
Oh and Jumcc, good job digging up a 9 year old thread, this board rocks!
