Let's play with some maths here.

   Assuming inflation where it costs 3 bucks a bag for ice, a $1200 budget,
and that you already own a cooler, Mr. Calculator tells me that you can
fill said cooler 400 times.

    And think of all the pumping and sparking exercises that you won't have
to go through, let alone pulling the stupid fridge out every couple of
years from a wall that it doesn't want to come out of, and is even more
reluctant to slide back into.

    If my RM182B ever quits, my mind's already made up.

     I'm certain your mileage will vary,
