I tried to sell my old prelude on fleabay with a £600 reserve and got nowhere. Relisted it without the reserve and got four offers over £600 in two days. If I'd let it run I'm sure it would've made over £1k.
Reserves seem to put bidders off and stop people from watching the auction over a period of time. I'd run without but make sure the start price is as low as you can stomach.
