I'm looking for a good (low cost I know thats a oxymoron

) tubing bender for custom building as in roll bars, etc. I would like a hydraulic unit but I dont want to spend a fortune as its going to be used just for my own projects and stuff. I liked the one they had on Muscle Car on Spike TV this morning but missed the name of the company who made it and its not on their site.
Thanks,
Mike
