I still have some of the flyers for "The Mark" treadle hammer. They were / are asking $1500 delivery included for the treadle. $850 for the "power pack" air assembly, or $2200 for both, delivery included. It looks like a good solid product but in comparison I like the style that seems to predominate here on IFI. The Big Foot seems to be of this style. For myself, it coming in a kit form, I would expect to pay less then a fully finished, pre-assembled product.
Thanks for the recommendation Tophand, $650 is a bit more than I would prefer to spend, plus I'd have to have 220 brought into the shop.
Welcome to IFI, go to the top of the page and click the User CP and show us were you are from. From your post, I'm assuming Oklahoma. :D
