He says he has $300 to $325 in his. I hope that includes the price of a die set, otherwise you can buy a bender for $300 from JD. I guess the biggest expense will be buying the 12 ton jack (Harbor freight). They might even have cheaper than the one's you linked too, since they don't have to be that big. I probably have access to most of the steel for one at work. Maybe even the shaft material. Definitely have the bolts. Might get off pretty sheep.
