    Just personal preferance and what i use here at the shop

    1 3/4 .120 wall regualr steel tubing (NOT PIPE) if you are gonna go crazy get cro-moly or DOM (i still havnt figured the difference.) you can make the reg steel tubing work. i know cor-mo and DOM is lighter but i don't feel the $$/ weight a benifical tradeoff for the budget minded.

    we have a JD-2 bender at the shop--regular ol' muscle to bend it. We have about 6 dies but use 1 3/4 and 1 1/2 the most so i would reccommend those 2. This setup IS pricey, but think about how much you are gonna spend on one cage.

    my $.02,

    DOM isn't lighter. It's HREW to tighter tolerances is all, the only thing that makes it different is the manufacturing process. It is also a welded seam tube.

    HREW is just fine for cages and stuff.

    I built my own cage and stuff this summer. I am no pro and did it all with normal fab tools (welder, chop, saw grinder, and a buddies bender). I found out two things, first you will waste a good 60 feet of tube before the thing fits the way you want it, second metal working outside with no shade during the summer in Phoenix really sucks. I used 2" .120 wall hrew tube and an m-tech bender, they are sold locally here so it was a natural choice. It is one of those hand benders. Some simple guidelines I would use if I did it all over again:
    Use 1.75 od .120 wall hrew. the 2 inch doesn't give that much more strength but it is a hell of a lot harder to bend. DOM is really not worth it, it is twice the price. Most fab shops use hrew anyway except when specified, or for highspeed racing applications. DOM -vs- HREW is like particle board -vs- plywood, once you paint and finish it nobody will really notice a difference. Looking into, and using, gusseting will make the cage much stronger.
