I have been looking at the fridges too, our is beginning to act up. Our fridge is 22 years old, it is a Kenmore top-freezer unit that came with the new trailer house my wife and I got when we married in '82. Never a problem until the last couple of months. Could probably fix it but the wife says after 22 years she wants a NEW one. Women - barely get something broken in and they want to replace it with the new style :-laf :-laf
Consumer Reports reviewed fridges in the February 2004 issue. Sub-Zero did not fare well in their reliability survey, 25% of owners reported repairs and serious problems, typically fridges of all sorts are much more reliable than this. Compare with Whirlpool or Kenmore for example that had less than 5% of owners reporting problems with top/bottom freezer units. The average for all brands was about 10-12%, so 25% is a significant deviation from the mean - must be some quality/design issues lurking. I didn't realize until I read the review that many of the high-end built-in units come unfinished, for $5000 you'd think they could provide a set of different finish panels.
