S.T.
I love HE machines and have had front loading since converting. The odor issue is a non-issue for me for the reasons listed below - keep the door open while not in use, wipe down the seal periodically and an occasional (and I mean very occassional) clean wash run with bleach. Typically I run a load of cleaning towels on hot/hot with bleach and call that a wash cycle; a two for one in my mind.
My biggest gripe about top loading HE machines is I can't stack them. I love stacking my set because it allowed me to add a 60 inch long cabinet to my laundry room. That is so much extra space I did a little happy dance. Also stacking puts my dryer on top which is really convenient as well; I can fold straight out of the dryer. Plus that fabulous cabinet I added gives me 60 inches of folding space right next to my set. Can you tell how happy I am about stacking my set and my added cabinet? :)
