We started to rent the refrig. at first, but they are so small and getting a bit more expensive than the $5.00 that we paid when we fist started. We then bought a plug in cooler and it worked just fine, and we do find some uses for it at home. I guess I would opt for the cooler if I had to make the choice. If you are just looking to cool milk, we once bought a hard shell bag, then put ice in it. Of course there are a few downfalls, like changing the ice all the time and such. We also used it as another way to get souv. home.
Good luck
