The GE front loaders are awesome! My whites are whiter and I can wash AND dry a ton of denim at once!
It seems like almost every type of laundry detergent has a 2x concentrated for front loaders so I'm sure you can stick with your fave.
I really like mine. I also don't notice a difference in wash times unles I add an extra rince cycle to my load. And the steam option works so nice for monday mornings (or any morning) you dont want to iron!
