I'd like to buy some ex-factory machinery.
Q: Is it worth the expense? Or, with electronic solutions to running 3
ph. machines from single phase power, is it not worthwhile?

You definately want 3 phase. Probably 220v. I wouldn't go with the
440v even though a lot of industrial equipment uses this. 220 is fine
for most uses such as for welders and compressors. Plus you can run
seperate 120v off each leg and get a larger load off the main line.
220v welders provide a much longer duty cycle and you can get a bigger
air compressor also.
The cost will be more because of the extra wiring and use of bigger
wire but you will be glad as time goes by and you need more
outlets.....and you will.
Good luck
