I looked at the HF benders, and (newb that I am) I didn't even notice that they're pipe benders (not tubing benders).

I was originally interested in the vertical bottlejack style because they have a build-it-yourself kit. The "Model 3" style by JD2.com looks nicer.

As far as degrees bend, the JD2 has 180 degree dies. The vert bender has 120 degree. I don't see any 240 degree dies for them. What am I missing?

No cages for me (though you never know). I'm thinking of roof racks, so tubing between 1/2" and 1" max.
