I agree Mark, Ebay is a place to simply advertise. Its a place to get interest from. No-one ever said ya had to leave it on there for the high fees. Plus, if a member comes into your showroom and offers you a reasonable amount for it, a seller would be crazy not to take it.
PLUS , a serious collector/player gets the pin, saving it for eternity.At least the machine will get serviced, new parts, and get to live long and prosper. Ok, i nicked that from spock.
But, after all, ya got to look after ya mates n fellow forum members. ofcourse.
Better than the pin going off to someone who wont look after it. ! 
I keep well away from Fleabay when I sell pins. I sold maybe 3 - 4 pins and then it became more of an advertising tool as the next 3 pins were sold outside of eBay. Most of the guys that bought the pins have kept in touch and I've sold a few more to them. One collector has bought 4 machines from me - all from viewing a pin I had on ebay, then leaving with another !
I prefer offering them here - then I KNOW they are going to a good home, and I can help out if there are problems.
Project pins nowadays are now selling for what working pins sold for 3 years ago.
