I hear you on costs.. I saw an awesome video of a guy that dedicated a chest unit for fridge and another for freezer and mounted under a flip top counter for easy excess. How cool! Then I saw what he paid... The old joke of I wish I had enough money to buy an elephant came to mind. Don't want an elephant, just enough money to..
I just saw a Whynter a few days back. $450 (about) and decent looking unit. 40qt size, and still seemed large for what it contains.. Power consumption claims 65 watts, yet said 4.5amps @ 12v.. My math goes a bit higher on amperage, but that's my math..
I didn't like that the 'freezer' is not isolated from the 'refrigerator' section. Weird.. Seems to me most are this way.
For me, cause I like to build my own, I'm researching buying the components and making my own case. I like chest style units and if you build out of, say 2 1/2" foam or heck 3" foam, think about how efficient it could be. I mean, go 3" and ice... think about how long that could last. Especially if you build two and work out of one and the other as the hold 'em unit.
Just some thoughts...
