What type or sizes of tubing do you plan to bend. I bought a used hydraulic bender that I used to make lots of rollbars, chassis work, etc. It was what was called Greenlee show bender I had to hand pump to make bends, and came with a number of shoes for different size tubing from 1.25" up to 2". It worked great but found some tubing that was a bit smaller than the various shoes, and that tubing bent well, but got slightly oval due to the smaller OD. This bender and shoes were for electrical tubing, but worked for a lot of other tubing also. Got it at a tool auction.
