I think you would get less than 10 cents on the original paid dollar if you sold it on Ebay.You will NOT get $750 for all that......
One year ago your $750 price would have been too low. With the bad economy, most sellers are surprised by the low number of buyers. Hardly anyone calls to buy stuff. You may have to start at $750 but be willing to lower the price to $400 after one week. If you are not prepared to sell it for that price, you will have to save up to buy your dream machine.
