I am deciding between the Electrolux EIFLW55HIW ($1099 less $75 rebate)and the Whirlpool Duet 9500 series (WFW9500TW)($1025) for second floor installation.

I've heard that the Electrolux is quietest and w/ least vibration for second floor use. It is also larger than the Whirlpool (4.7 vs. 4.2). However, I am not sold on the Electrolux automatic touch door. It looks like it might have problems in the future (sticking or not closing properly). Also-- the whirlpool has steam in the washer and dryer, while the Electrolux does not. But I just read here about some problems with the Whirlpool Duet and musty smelling towels. Any ideas?
