Oddly, most all contractors saws take up slightly more space, due to the motor hanging out the back.
Otherwise, the contractors, and cabinet saws have the same foot print.
Now just my opinion, as I started out with a contractors saw.
Contractors saws are a poor design, the motor hanging out the back is a source of vibration.
They are a pain to keep aligned, due to the way the works is bolted under the table top itself.
The cabinet saws run smooth and produce a better cut finish.
Yes, they weigh about double, but, they can be quickly taken apart and moved down a flight of stairs.
If I had it to do again, I would have never gone the contractors saw route.
I was so frustrated with the contractors saw, I went a step beyond the the cabinet saw and picked up this 14"-1000lb saw.
Now, the regular cabinet saws are just too small!
I knocked this apart, and moved it into my basement work shop!
On the 110volt problem,
A fellow I know did this. He found a Powermatic model 66. those saws use a common motor mount. He pulled the stock high volt motor and installed a 1 1/2hp 110volt motor and switch.
Since he had a contractors saw and used thin kerf blades anyway, this worked out well for him.
the Powermatic 66, is a great saw.
