If I had $9000 to drop on a lathe, I don't think I'd be using it on the new Grizzly / SB Heavy 10, but for somebody with the cash and lacking space for something bigger it is a pretty big advance over something like a Grizzly or PM 1022/1030.
543lbs vs 330-395lbs
1-3/8" spindle vs 1"
2HP 3ph (with VFD) vs 1HP 1ph motor
D1-4 camlock vs threaded spindle or DIN flange
10.75x30 vs 9.5-10x22 or 30"
7" wide bed vs 5.3-6-1/8"
Quick Change Gear Box vs change gears
Made in Taiwan vs China
Lots of other options at the $9000 budget level but it does look like a pretty nice lathe for someone that is cash flush, and space deficient. Although at 61" long it is only a few inches shorter than the PM1236-T for about 50% more money, that is an expensive couple of inches.
I think there are at least a couple of members here who have one of these lathes who might be able to comment more specifically on the quality, I can just window shop the spec sheets.
