I’m not familiar the exact model, with but “Craftsman” is enough for me to avoid it (sorry to offend, but it’s based on my experiences with several C’man ww’ing machines). But, it depends on your requirements, your standards and your budget. I’m not saying they won’t work, but you’ll find out the accuracy isn’t there. Just my opinion having used one, others may think they are great.
I would point out why I say this. One, the trunnions are not cast iron and it is mounted to the top, both are signs of a higher quality saw.
Second, fences that clamp between a front a rear rail as no rear rail are not nearly as accurate.
I would definitely avoid the 12” machine. 12” blades are usually on 5HP machines. They are also considerably more expensive to buy and sharpen.
I’m only mentioning this to help give you an idea a there are some things to consider before buying one of these machines.
As a guy who actually owns and uses 3 of them I have a bit more experience with them than you do.
Regarding the 12" direct drive or "motorized" saws, where the armature is actually the arbor, not a gear or belt drive brush type motor:
The trunnions are cast iron. They are mounted to the underside of the table as are most cast iron contractor type saws.
The saw will accept 10" blades and that what I use. The arbor is 5/8" a common size for 10" table saws.
The difference in sharpening costs depends on the number of teeth, not the diameter, at least at my sharpening service.
Either saw of that vintage will have a crappy fence, so that's really a draw.
I don't really care which saw the OP chooses, I'm just sharing my experience of owning these over a 40 year period. FWIW, my first table saw was a Craftsman 10" contractor saw with a crappy fence, purchased in 1960 when I was 18 yrs old with HS graduation money. It never blew up or wore out, but I eventually parted it out when I got the 12" saws and wanted the table for a spacer between them and I still have the wonderful, heavy duty 1 HP motor for a spare. FWIW-2, I also have a newer 10" Craftsman 22124 hybrid which is a great saw which came with a Biesemeyer fence, and is very accurate.
