Here is a pretty recent review and comparison that includes the Whynter

We just bought a fridge and were seriously considering the Indel B.
Wound up getting a decent enough deal on the ARB 50 and bought that.
I figured I was going to buy and keep one fridge for the foreseeable future, so I paid the $767 to get the ARB; as I heard their after sales support is very good.
I am sure that whatever fridge you get will be pretty solid, and I haven't used my ARB, so no real firsthand experience.
Supposedly the truckfridge and the ironman ice cube are the same as the indel B, or at least look the same and have the same danfoss compressor.
If you want way more (too much) information, opinion and confusion, head on over to the expedition portal forum in the camping gear section.
