For appliances, my wife and I have started to purchase commercial products. Right now, all we have is a microwave, but we were tired of constantly having to purchase a new microwave every 5 years or so, as things broke on it. Our previous microwave, for instance, still worked ok (ie - it heated up food ok), but the turntable lazy-suzan thing had paint problems: the rollers of the lazy-suzan, where it fit in the track, chipped and "grinded" the paint, so there were paint particles and fragments under the glass surface. We'd wipe it out, but more would occur. Eventually, it wore a "rut" (no more paint chip issues), but then it started rusting from food moisture.
So we dumped a bunch of money (close to $300.00) into a commercial microwave. One knob, 6 minutes max, high power only. Honestly, it works perfectly, easy wipe-out interior surface, no turntable, but heats evenly without turning the food. The only downside with it (as with all commercial kitchen appliances) is that it is stainless steel only (we have a "white appliance" kitchen.
Our next purchase will likely be a commercial refrigerator, and a replacement freezer. We're going with only a refrigerator in our kitchen, and replacing a small chest freezer in our garage with an upright. It's going to cost a helluva penny to do this, but considering how much a new consumer side-by-side costs anyhow, it should be worth it in the long run. The only downsides we have found (so far) are that a) commercial refrigeration units are much taller than consumer units, and we're having problems finding one that will fit into our current space, b) commercial units, if used in a home, usually will void the warranty, c) commercial units need commercial repair service, which is much more expensive in parts/labor when it does happen.
But we thought we'd give it a shot. Our current side-by-side works ok (mainly - water dispenser and ice maker don't work anymore), and it has worked well for 15 years now (and was bought used when we got it). Part of me wonders, after reading this story, if it might be better to have it repaired instead. We've already seen prices for new units, and they are crazy expensive for what you get. Plus, most of them don't fit in our current space; they seem to be made for new houses, which have taller ceilings, and no overhead cabinet above the fridge area - unlike our 1970s ranch-style home (Why do we live in such an older home? For starter's, we live below our means, because it provides a bit of insurance against uncertain problems. We also wanted a house without an HOA - new houses where we live, without HOAs, tend to be custom construction, if you are lucky, and that was beyond our means at the time for our first house. Lastly, we wanted block construction, copper piping and electric, and better construction - houses today are built so damn cheaply).
Hopefully whatever we decide will work out in the end. But so far, we wouldn't change our decision on our microwave (ours is basically the same one used in much of restaurant service - Sharp and Amana make the majority of these).
