I paid $1,100 for my Bosch 500 series dishwasher a couple years ago. The current generation looks like it's on sale for as low as $800. Yale Appliance shows Miele dishwashers currently starting at $1,400. With that kind of premium it should feel better. And, yes, the Bosch feels super cheap.
Miele washing machines start at $1,600 about twice what an entry level LG would cost. While I would never buy an LG, they are generally well regarded in terms of actual washing performance.
