We have a dish draw and while it's great if you are happy to just do your plates, bowls etc it's not good for the bigger stuff like pots as they take up too much room. I used to put all the plates and pots etc in my old dishwasher but now I wash all the post separately as I don't want to run both draws. Thats just my opinion I know others love them.
Oh and if you can afford to get two separate TOP draws it's better as we hardly ever use our bottom draw Too Lazy
