It's his lookout if he sells at a loss, you just can't win; put the prices too high and people will shout you down (not mentioning any names) when they have no intention of buying, too low and people will complain you're only after 'fast cash'. I notice you have a DM6 from your sig', you accuse the seller of being being selfish (not in so many words), yet your reasons for posting about the price is purely selfish, you have vested interests in the DM6 market.
Good Luck with the sale AJ, ignore the bellends
