Do not get one with auto water level sensing. I received one as a housewarming and I hate it so so much. I've broken into hives because the chemicals do not fully wash away.
I think just about every one I have seen has this feature.
I am also now looking at the Bosch 500 series, look pretty good and I can get the W+D @ a pretty good deal for about $1800 (instead on $2300)
