Lucy --
The DC04 went for £264, which wasn't a bad price, I am bidding on the other DC04 Zorbster, but I will no doubt be outbid, as Josh has expressed an interest in it. I expect the DC01 to do very well, but ultimately you have to decide whether to pull the listings and sell privately. As you have seen - bids go crazy in the last few minutes, and there will be undoubtedly a lot of watchers on that DC01.
May I suggest that you always start the bidding at what you expect to get for each item, then if it doesn't sell, you will not have lost money on it. Starting items at a penny with no reserve can be a huge risk
