What should I expect the resale value of an Ampeg B2R to be?

Hey TB community, I'm perplexed, I'm trying to sell my Ampeg B2R and obviously get as much as possible for it to fund my next aquisition. The trouble is I cant work out a price that will attract a buyer. I'm in Australia and tried to sell on ebay recently at $1050aus, I got lots of watchers but zero bids, now some dude has put his on at $820aus and is ending his auction later than mine, so I dropped mine to $800aus to get a bid and still nothing! I realise that with all the mid year sales on it could just be bad timing, but c'mon! What should I expect the resale value of an Ampeg B2R to be?
