One thing you should consider is having 3 phase wiring installed. If you add new service, it can be used for other tools in the future. I don’t know where you are located, but if you’re in a rural area the cost will be prohibitive, but if you’re in an urban area, or close to a school, hospital or manufacturing district, it might be worth looking into. If you’re close enough to a 3 phase transformer, it could cost you as little as replacing your existing single phase service, which around here means about $2k (new drop, new panel, meter, grounding, etc – not including circuits). Could open up a new world for you.
I sometimes hear about schools selling shop class equipment which is really industrial stuff – all 3 phase, and cheap. And on Craigslist, the 3 phase stuff often goes for cheap because there’s a much smaller market for it. Anyway, food for thought. It really all depends on the direction of your business in the end.
Good luck with your search. New toys are fun. :-)
