IIRC there were a lot of people on mechmarket that were more than willing to buy the entire set... why the ebay auction?
My main reason for doing the auction was that I want to get rid of all the kit in one go. I guess I was wrong, but I expected to get 10 messages from different people wanting different parts of the kit, and have the hassle of packaging & posting to separate places. With an auction you either bid on the lot, or nothing.
It also allows buyers to determine what cost they are willing to pay, rather than me negotiating with potentially several different buyers. It's more about the convenience to me rather than squeezing the most profit I can.
