Hi Falcon,
Welcome. I have an X3 from Lathemaster and am very happy with it. Didn't think I had room for the bigger one or would have gotten it. Plus I wasn't wanting to have something that heavy in case I needed to move. I have heard nothing but good about all Lathemaster products and have an 8x14 lathe on order. Check out the Lathemaster forum if you haven't already, there is some recent information on the big mill there.
