I have a 64 quart Engel that has been back and forth to Baja (same beach as Scatter) about a million times and just got back from a trip to Death Valley. It works perfectly after probably 15 years. Having said that, I think that if I replaced it or augmented it with another, I'd probably get a National Luna next time as it has a Danfoss compressor which I consider to be superior to the swing-motor in the Engle/ARB/Norcold (like I have now). Of course the NL is also about twice as much money!
