If it were a one-day deal or the like, I'd agree with you, but I'd
choose refrigeration in a heartbeat for any regular use. I'm intimately
aware of the hassles of salt-ice refrigeration, and I'm quite certain
that if I were making ice cream and sorbet as a busness rather than for
myself, it would be an easy decision to spend the money for a
refrigerated mixer - for home use it's a lot of money, so I use salt and
ice.

Another approach would be to use a solid state cooler and a bit of
compressed air.

Peltier Junction Thermo Electric Heat Pump

One could refrigerate a jug of water for a few days
then use it as a heat sink for the copper tube.
That'd be inefficient but it might be cheaper
because it would eliminate the trip to the store
for bags of ice.

I like it.
