I don't know your budget... or if you plan on doing this sort of thing more then once, but I have always been a sucker for GOOD tools, and never mine did saving for them. If I was to buy a Tubing Bender it would not be from Northern Tools, nothing wrong with Northern Tools, just not for a bender. I would look around and try places that sold professional fabricating tools like Trick Tools, they have everything from pro to beginer.
I recently purchased a bending outfit from them and they are a joy to work with, both before and after the sale. A good bender represents a huge financial undertaking, and you'll find the bigest expense is the dies, and not really the bender itself.
I bought the JD2 Model 4 Bender with hydraulic power, cart and 6 sets of dies. So far the bender has worked great and is everything I wanted. Good luck with yours.
