If you don't like those choices for whatever reason (such as, I don't know, the design sucks), your only option is to go to the high-end, and the prices there are outrageous. There is no middle ground. It's kinda ridiculous.
My first thought is that there is untapped potential here and perhaps I should be in the mid-range refrigerator business. My second thought was that there probably isn't much of a market. That is, most people are not going to be willing to pay much over 1K for a refrigerator- their need is to keep something cold and they aren't going to overly fret over the details. Those who want more, well, generally they want top shelf and so top shelf caters to them. Those that want "more", but not necessarily "all" are going to be a much smaller demographic, probably for most products.
Of course this is just speculation on my part, but I figure that if there was a market there then there would be refrigerators at that price point.
My own tendency is to look for the cheapest thing I can afford, realize that it doesn't have everything I want, then once I find the really expensive thing that has the feature I want try desperately to justify the purchase (which in almost all cases is a bad choice). Sometimes good sense wins out, but often my lack of will power ends up in a poor purchase just because I want one specific feature. It feels frustrating to pay good money for something that isn't quite what I want, and somehow less frustrating to spend gobs of money to get more than what I want. And perhaps there are enough weak willed people like myself that it makes more sense for companies not to offer the mid range options to force them into the upper echelon.
All that being said, fortunately refrigerators are not a weak spot for me. As long as it keeps stuff cool, I'm in good shape.
