My advice is to get a bigger one than you think you need.
I like the LMS for the belt drive, brushless motor, solid column, air spring and slightly larger table.....
Can't go wrong with a Grizzly, though Quigs would be a better source for pros and cons than I, on that one...
Not sure about the taig.....
Wishin' I had just got a bridgeport and been done with it........
No used machines around here unfortunately or I would just get a big knee mill . I don't like that the grizzly uses mt3 tooling...... the LMS seems to be the best machine in the x2 size.
The x3 size starts getting into pretty substantial $ outlays.....
