I've seen blenders for anywhere from $20* to $2,000, and I must say, the variety of marketing-speak has my brain in a tizzy. In plain english, what are the major price levels in blenders (general ranges, obviously there's some variety in quality at each price range) and what sort of features can I expect at each level? For example, I'd not expect a $20 blender to, say, heat up soups like one famous (but more expensive) model is known for.
* I use USD, but I can convert prices easily enough
