FYI, Westinghouse is now just a brand name that's licensed to an otherwise totally separate company. There are many older brands with similar license arrangements - RCA, Zenith, Polaroid, etc. The original companies went out of business years ago but the names live on through license agreements because they still have some brand recognition.
I'm not doubting you've had a great experience with your Westinghouse set but everyone should be aware that when you buy such brands it is a crapshoot as to what quality you get. Even buying a product with the same model number is no guarantee that the components inside are the same.
After warranty support is often a big problem with these brands too because they source their parts from all over the place, typically getting the cheapest ones available at the time, so they don't usually have access to any replacement parts after they've exhausted their inventory.
Unfortunately we're now seeing a similar trend with some of the big brands too.
