Snagged a few transformers for cheap off eBay. Went to pick them up a couple months ago in NC from a surplus industrial place.
Ended up getting a 7.5 kVA that is going on the boat (HS14F7.5BS Pri 190/220 Sec 120/240). It's an international model with a ton of voltage taps, and can take as low as 190VAC input. When I opened up the cover to look at the wires, I confirmed it is brand new and never installed! I think I paid like $140
Using a smaller 5kVA temporary right now.
