I have one of these, and it works OK for 1/2" pipe,
of OK for 3/4" pipe, and I've never tried anything
bigger. Don't forget you also need a big vise with
the proper jaws to hold the pipe.
The threads it made were not perfect, but a lot of
those pre-threaded lengths at Home Depot had pretty
mediocre threads, too.
I managed to do my setup with pre-cut lengths
and unions from HD.
