You can get an ok bead roller from Harbor Freight. Its on sale right now for $89. If you order it you will not have to pay for shipping, but they do have a $5 handlening fee now. Bead Roller at Harbor Freight Now if your just looking to make straight bends in metal you want a Sheet Metal Brake. They very in length and how thick of steel you want to bend. The best kind is a Pan & Box Brake, this will allow you to do corners and will allow bends much farther than 90%. Harbor Freight has them to but they tend to run into real money. They even have combos, you can get a combo shear, brake and roll. If you need all 3 of these things it might be a good way to go. I have the bead roller and will be getting the 48" Pan & Box Brake soon. Now if you want to make 90% bends in a curve, like the lip to a fenders wheel well then you can get a sheet metal Shrinker - Strecher from a company like Eastwood Company. They are a bit up there, like $300. Hope this helps! Look in hot-rod and custom mags for books on metal fabrication to.
