In reply to djwilse:
I sold a pair of Terrordactyl hammers a few months ago for about £50. I recently sold a Terrordactyl adze signed by Hamish and it went for about £60. In this current financial climate, prices are quite low for this sort of thing. A few years ago, a pair was about £80/£90. I was a bit disappointed the signed axe didn't go for more, but perhaps it serves me right for not having a longer auction on Ebay or setting a reserve. Anything with 'Chouinard' stamped on it goes for a bit more.
I like the idea above of negotiating with a pub/free beers!
