I was comparing them on youtube. the G0704 is a little heavier and has a high / low speed selector switch versus changing the belt. But otherwise the PM looks super nice (and is quieter due to the belt drive and maybe a tad more powerful due to brushless motor). I'd love to have either one. I don't hear anyone complaining about the G0704.That linked mill looks exactly like my Grizzly G0704. I didn’t get a DRO, but I’ve been happy with mine so far.
