Actually, it was Nate who gave me the nudge on the '57 Combo. I was going to pass on it since it wasn't 100% frost free.
The more I thought about it, the more I liked the revolving shelves, and it has way more bling than the '70 Whirlpool it replaced.
Nate was on board for a road trip, so off we went!
John, I did replace the temperature control on the Combination, and it seems to be the weakest link on GE's from this period if one considers lasting 50+ years a weak performance. I had the rear access panel off and didn't see any obvious evidence of compressor replacement, but I wouldn't rule it out since you have stated many times that GE had problems with them, I believe while the majority were still under warranty.
Travis, as has already been stated, if someone has money to burn and prefers to buck the trend by opting for a retro look, then yes, this Amana could be the fridge for them. They'd likely be able to afford domestic help that would keep a significant layer of frost from ever accumulating in the freezer.
