I'd get a few half totes. $500 each, but you can' break them. One of those "once in a lifetime" expenses. They hold ice really well too, as well as serving for a dry place to store lots of gear, when not being used to ice meat. I use mine for commercial fishing, camping, hunting, etc.. and they can't be topped.
