Bosch is a good brand.
They are quiet, get the dishes clean, and are incredibly efficient with respect to water and energy use.
They take about 2 hours to go through the cycle. If you have anything with a lip on it, such as the bottom of a coffee cup or the edge of a plastic container it will come out a little wet.
For the different models of Bosch, look at the dish rack configuration and how you would plan to load it with your dishes. Mine isn't ideal for our dishes, but it works well enough. I'd pay $100 more for a better rack configuration though.
