I'm confused about not having another source of 220 power at the house. Is the electricity off? I would think a 10 gauge extension, or if it had to go a long way, an 8 gauge extension, while expensive, would be better than killing the saw. Is there not a dryer outlet you could commandeer when you need to use the saw? I'm guessing there is part of your current (no pun intended) situation that would keep you from doing this, and it just isn't clear to me, but I felt compelled to ask.
If you do need to get another mag switch, nothing saying it has to be the one from Grizzly, if there is another brand that will work that is the right rating and is cheaper, I think I'd go that route. I haven't priced mag switches, so the Griz unit may be very well priced.
I think I'd search for alternatives to power the saw. Building something small might be worth the risk. Building a set of kitchen cabinets would not be under the current (there's that word again) conditions. Jim.
