"Expensive" is a freezer full of beef, Elk, or native trout. A Couple of disasters have me ripping the original plugs off of appliances at risk of disasters. I use 10/12 gauge #6 spade terminals, solder them onto the wires then clamp them bejesus tight with the screw. It turns out to be a "you bet your life" lifetime connection. No fumbles, no excuses.
All it took decades ago to set the mouseketeer grade garbage original appliance plug lack of integrity. The 12 receptacle utility bar across my work table has spec grade sockets. The changed cord plugs are all transparent green dot hospital plugs. The interiors were painted with 3M conformal coating. They've lasted forever in a sopping damp salt air environment.
