I am looking at getting the grizzly model g9729. My questions are if it is worth the price premium over the harbor freight model. I cannot see this machine swinging a 17 inch part is all I'm thinking. I don't want the mill section as I am getting a seperate unit G0519, but it is there so it may get utilized. It is by far the largest swing in my price. even if it can only swing plastic at that size it is something the others cannot. there are always trade offs but what do you guys think? no production stuff just prototyping and one off parts for a gantrey table project.
