Flenser,
I got my RF31 back about 1999 and for the most part have been very happy with it. It now sports a VFD and 3PH motor which will give me speeds up to about 3700 rpm. Also made a power lift for it because the manual crank was a PITA. I have also cnc'd it and it is a workhorse for me. Back then, a 45 was just to far out of reach for me pricewise. If I were to to it over today and it was going to be my only mill, most definitely I would look at a 45 type of machine or something else maybe.
