Check the cost of 3-phase. A Bridgeport just doesn't use enough power to make
this usually worth the expense. I only has a 2-3 HP motor and you can use
either a rotary or solid-state phase converter.
Now, if you were considering a large welding operation or a plating line, then
3-phase is wise!

We're in the middle of a sizeable remodel on our house, and in adding up
the electric and gas requirements I'm looking at something close to a 400
amp service (of course, that's not just the new shop...) and enough gas to
feed 600K Btu of stuff.
I'm trying to figure out whether it's desirable to talk to PGandE about
putting in 3-phase power as a hedge against my scoring a decent used
Bridgeport sometime in the next year.
