I have a similiar setup. X3 (standard, not super) converted to cnc which works well for my need (did not need head tilt or threading) it is good rigid machine with decent travel. I also have emco compact 8 with lot of tooling that I bought used. I would have gotten one of the grizzly 10x22 or 11x27 that you are looking at if I did not get this emco. I have to admit that emco quality is fair bit better than most chinese lathe, but grizzly do have good stuff.
I think you can't go wrong with what you are planning, as you will also need to buy tooling. (which will add to the cost) frankly, I won't be upgrading to hass or bridgeport anytime soon. I have 2 CNC routers that does bulk of my work which is fine for my need. just really depends upon what you are planning to make.
