I've never noticed any water staying in mine (Frigidaire Gallery). I'm not sure how big it is.... it just says Extra-Large Capacity...
I believe it adjusts water amount to the load as well, and even though it looks quite small, unlike a top loader you can stuff it quite full and it still washes fine.

BTW - check with your local utility. On this side of the mountains we got a rebate from the utility company for buying a low water use machine. That and the savings in water and electricity made buying one a no-brainer.
