My local Snap On guy would begin referring to me as "Mr. BK"! Probably the same as everybody else, depending on how big the windfall was... If it is big enough, get the heck out of the city/suburbs, build a stick built shop/garage big enough to park a pretty good sized jet sled, my Jeep, and a full size longbed crew cab pickup. Divided area for a woodshop. Plumbed for vacuum on the wood side, and a big compressor plumbed with a lot of outlets on the other. Lots and lots of power plugs, 220/240v outlets for welder/plasma cutter. More modest windfall, I'd get all the M12 and M18 tools I want: 12v... Fuel 1/4" impact wrench, 1/4" and 3/8" ratchet, Fuel drll driver(non-hammer), Fuel screwdriver 18v... Fuel hammer drill/driver, impact driver, 3/8" and 1/2" impact wrench, 1/2" high torque impact wrench Euro 4.5 and 5" grinders, Fein, Metabo, or Bosch Tool box... HF 44" and/or 56", Snap On KRSC46 cart.
