I think this is the guy I got my son's Haro Zippo off; he had the two rare DPs at the time. Not sure if he is a list member but very nice guy.
I think the Pit and the Mini are worth 1k to the right person but not too sure about the Mk1 as that seems to be a pretty standard bike.
But like you Ed, I could easily add a DP Pit to my collection but cant afford it..
So, come on "teresa2600" - say hi!!
PS: did the Zippo come with a guarantee as its currently got a flat tyre
