It would be nice with a quill feed. I bought one when they first came out (about 2011). Was nice, when it was the only thing I had. But a little bit later I picked up a rongfu 45, off Craigs list. I have only used the grizzly a few times since. Then later, I got the Van Norman 22LU, and only used the rongfu a few times since.
You need to mount it on feet, or something where the Z axis screw can go lower then the body, you will get about 2 more inches of Z axis travel.
I would not bother, unless you are tight on space, and nothing else would fit.
