Metal bender

It sounds like you are concentrating on a round tubing bender and in
defense of the Hossfeld, the one I used came with dies to bend almost
all of the standard metal shapes (angles, box, channel , etc.) and was
VERY flexible. Yes it does take forever to set up and is hard to get
repeatable results, and lots of scrap sometimes to get what you want.
Fundamentally, does the customer want lots of flexibility or lots of
repeatability? All of the tubing benders on the market for "home use"
are fairly reasonable priced as long as you are bending one O.D. of
tube, the same diameter bend all the time. If you buy a "Tube Shark" or
one of the other lower priced units out there right now, you will go
broke buying dies to get any kind of flexibility.
The Hossfeld has what I call "multi-pull" dies which allow you to
bend a wide range of stuff by manipulating the workpeice manually
between bends.
Anyway, after much rambling, if I was buying one for the home shop,
I would be looking for flexibility with lots of different setups
available in the base model. I'm not as worried about repeatibility for
my type of work.
