I have a JD2 bender and it works great. I have had it about 15 years. If you are planning on building more than one cage I would go with one of these with the hydraulic cyl on it. It can take a lot to bend all those parts for a complete car. You probably won't need more that 2 or 3 different dies. If you start doing jobs for other people then you can buy more dies as the money comes in.
