Honestly, I have no idea how the GRizzly knee mills compare. They are most likely made abroad. I own their X3, but this is only a benchtop mill. THe quality is top notch in my opinion. They slack a lot on the non critical stuff. Maybe the mills closer to the top dog on theGrizzly's site are better with that too.
VMC's are great, thats what every shop now uses. I just hope you know how much they cost. Like I said, its not worth it unless you are doing some sort of business. These things run off 240v as a minimum.
Here is a typical example:

The newest one at work is beautiful. Its got all the bells and whistles, 35HP motor, and cost about as much as a small-medium house
