This the mill I’m considering http://www.grizzly.com/products/G0463
I also considered the http://www.grizzly.com/products/G0704, but after visiting Grizzly and comparing both, the deciding features were the standard bolting of the column to the top of the base and the more rigid appearing column of G0463, apparent in greater weight. The G0704 bolts the column to the back of the base.
