Can't speak for others, but I rarely buy the cheapest option for any kind of appliance... some, sure, when there are not any truly better options. I mean, I don't necessarily want to go all the way up to commercial models, but there's got to be some room for in-between.
I remember buying a washer-dryer a while back and the sales person was like, "this is kind of the Cadillac model." To which I responded, "what do you have in a Buick?"
It just sucks pretty much knowing that the "X-year" warranty won't actually cover the control board that changes every model year that is the most likely thing to break just outside of warranty anyway, or even if sooner, you won't be able to get replaced.
The main burner went out in my range (top cracked) and I'm pulling my hair out on picking a replacement oven/range... There are too many options, and quality is all over the map, even in the same brand/model from year to year. These things should have lifetimes measured in decades.
