A.,
I bought the Maytag Epic series from Home Depot and am so happy with them. Whirlpool actually makes them and it's the same washer and dryer, but they sell for less with the Maytag brand. (Long story; bad reputation with the Neptune series.) Anyway...
If you are looking for ways to save money, you picked a good time to buy. Now is about the time they go 10% off at Home Depot and offer free delivery and take your old ones away for free. In addition, about this time of year Maytag does their mail in rebates. Also, check with your electric company. Ours gave a $150 rebate for buying them because they are so energy efficient. I ended up paying about the same as for the old fashioned kind after all the discounts and rebates.
I would recommend buying the pedastals to go under them. They prop the washer and dryer up to a natural height so you don't hurt your back. My friend gave me this recommendation because she said she regretted not buying them as soon as she used the washer. And it isn't something you go back and get later. It is tricky to install after the washer installation and can break the washer. Do it at first or don't do it at all.
Lots of people say you can put small amounts of regular soap in a high capacity, but don't do it. I have been told it works great for about a year or two, then causes problems and you void your warrantee if you do it. And don't close the washer door all the way when not in use or it get's smelly like mold. Just leave the door ajar and let it breathe.
Good luck. I hope you love your washer and dryer as much as I love mine.
