You really need to make a phone call to your power supplier. I just had 3 phase installed into my shop for the exact reasons you're talking about. Most people here told me it'd be too expensive, and would be a waste of money. I knew I had 3 phase 175 feet from my shop, so went ahead and asked. The power company hooked it up for free. Even supplied me with a 200 amp fused connect for free. It is an additional $16 a month meter charge for the 3 phase.
I did the trenching, laying conduit, and wiring myself. I figure it cost an extra $1000 for installing 200 amp 3 phase vs. installing 200 amp single phase. Required extra wire, larger conduit, and more expensive panels. Am I glad I went ahead with it? Absolutely. I've already picked up a 3 phase commercial air conditioner for cheap, and got a good deal on a large 3 phase air compressor, and welder. I'm planning a shop expansion next year for space for a lathe and mill, and an indoor wash bay. Lots of options out there if you have 3 phase. Of course there are other options if it's not available, but there is an initial cost associated with all of that as well as a maintenance cost. Anything is possible. Just takes time and money, like everything in life.
