Sub Zeros Have always been very reliable
WOW, I have never heard of anyone that called SZs reliable, you are smoking some good stuff Bruce.
That said SZs are nicely designed and usually good performers, but they are Very expensive to buy and service and will need a lot more service and repair in their frist 30 years of use than just about any other good domestic refrigerator.
If I were doing a kitchen now and wanted a nice built-in ref I would look first at Kitchenaid, KA is still expensive and not always the most reliable but usually better than SZ.
Diffidently avoid GE Monogram and Viking BI refs at all costs, but of these manufactures have been nothing trouble in the BI ref arena.
When you are spending $5000-10,000 on a ref keep in mind that this is not the last money you will spend, and as always skip the service contracts, if you can't afford to have it fixed you should not be buying this appliance.
