I got one when I got tired of waiting on a friend to bend some pipe for me. Best thing I did. 1-3/4 1-5/8. 1-1/4 are all the dies you need. Works nice, once you get the layouts or templates right it goes quickly. Sets up and take downs are quick, I mount mine on an angle iron and bowling alley bench, (3x10) that's bolted to the floor. If I ever start bending DOM tube I'll get the hydraulics.
