I just want to reiterate the pros that others mentioned for the front-loaders.
They are more energy efficient, water efficient, use less detergent, get clothes cleaner with less damage to the fabric, spin faster to remove more water, hold more clothes per load, etc, etc.
Mine is a 4 month old Maytag Neptune, which I bought even after the whole lawsuit issue, and have had no problems whatsoever (I did purchase the extended 5 yr warranty, tho, just in case). It does have a feature where you can pause the cycle to add or remove items as needed, so I've never had that problem.
Yes, you do need to be a little more diligent with the care of the front-loading machine, however. You should take care after each day's last load that you wipe out the rubber flange at the front of the door, as well as the detergent/bleach/softener dispenser. As logic would dictate, any water that's left sitting in the dark with little or no air circulation will get smelly and eventually mildew. Simply wipe out the wet areas and leave the machine open for a few hours (in fact mine is left open a few inches almost all the time). In reality, even top-loaders can get smelly and mildewy if there is water left sitting in the bottom of the drum. I also left the lid open with my old top-loader and have never had problems with that.
I truly have nothing but good things to say about my new front-loaders and would highly recommend them to anyone.
