I forgot to say with our LG - you can do a half load, you can select the bottom or top half, and it takes around 1/2 the time and uses 1/2 the water... We normally use it on bottom half with big pots if need be, and you can apply the half to any cycle type (i think?). Also, get one with a time display, so you know how much longer you have left, and also get one that you can take the filter out easy and wash it - we empty ours out (it has 2 parts to ctahc a lot of extra stuff) after every few loads, it also helps to make sure the dishes wash well otherwise you just have that stuff going back around.
