Whirlpool Duet!
We have the Whirlpool Duet, they were a wedding gift 5+ years ago and I still LOVE THEM!!! I cloth diapered my son with them, the washer has a sanitary cycle with a hot water booster (so your regular water heater doesn't have to be set too high).
I love them! The washer is a front loader with a huge opening, so it's no trouble to get twisted clothes/sheets out. Both washer and dryer are high capacity, so very large.
But the washer has a sensor and only uses as much water as the load needs, so I never worry about using more water or detergent than I need. And it uses so little detergent! I use less than 1/2 of a regular Tide scoop (it ends up being about 1/4 cup). And when I have better detergent, such as Country Save, I only use 1/8 cup detergent for each large load (think queen sheets plus twin sheets plus an armful of clothes!)
I LOVE THEM! I should be a sales rep for them (but I'm not!)

edited to add: I also have the pedestals/drawers that go under the washer and dryer and really, really, really like having the washer and dryer a little higher up. I also like that I can keep my detergent, oxyclean, borax, vinegar, etc in the drawers, so the stuff is easy to reach and out of sight!
