A cabinet saw has the motor contained within the cabinet under the arbor. They are usually the more expensive, solid designs.
What Craftsman sold by the millions and Delta later termed a "contractor's saw", has the motor hanging off a bracket behind the table. They can be solid saws, just not as much so as a cabinet saw.
The 20-40 year old 10" Craftsman tables saw with a front mounted 1½-2 HP motor are really more than adequate for any home gamer.
We're sure he really meant "rear-mounted". Agree, they're solid saws which with a bit of fettling can do anything a homeowner needs done. Again, watch for the 10", as there are a million 8" and 9" versions still thick on the ground. I'd argue most real 2-HP motors are too heavy for the mounting bracket. I've seen several brackets and trunnions broken by too-large motors. It's the weak point of the design and a cast-iron 1-HP is plenty for a C-man. (The later sheet metal "2-hp-developed-starting-torque" frauds are a completely different piece of junk.)
Decide if you want a user saw or a showpiece. For a user, $350 will buy far more saw than a Unisaw Junior. Sometimes a Unisaw comes along for that price, but watch for 3-phase motors.
