Coolidge, I almost went down the path you are going down.
I started looking at the G0709 14x40... and than decided I would be sorry if I didn't get something with a bit more mass, so started thinking about the G0509G... and then heard about the RML 1440 lathes, and thought that would be awesome...
And then I figured out for the extra $$$ I would spend on the RML1440, I could buy a G0709... and a Tormach 1100 cnc mill (which I did). And then I could buy the Tormach slant bed cnc lathe in another year or two (which I haven't done yet). Yes, not industrial machines, but I figured I would have them NOW instead of someday in the distant future, which was all my lusting after Haas mini mills was going to result. I figured that if the day came where I was making money with my machines, that would be the point to step up to an industrial cnc machine.
