This misses the main issue rather badly: If he doesn't have 3-phase
power
available to him, then buying a machine with a 3-phase motor doesn't
make any
sense at all. In which case, the resale penalty won't be terribly
high, as
he'll be selling a new, never-used tool.

There is always the pahse converter route. A rotary unit can be built or purchased. A 5 hp unit can be bought for about $500.00.
This does, however add a significant cost to the machine. It really only makes sense if you have multiple 3-phase motors that you
need to power. In that case, one probably will want to get an over sized unit.
