Compressor is replaceable. Also, how do you judge reliability of a compressor before buying it?
Instead, try to find a refrigerator with access to the cooling pipes. Last fridge I threw away had a leak that couldn't be patched because the pipes were all embedded in the plastic walls of the fridge.
Yeah I think the caveat is that the compressor and maybe seals, lights and few other bits are the ONLY repairable parts of most fridges. The whole structure of a modern fridge is foam panels and sheet metal folds that aren't ever meant to come apart after being assembled.
