If you're considering a Duet, don't overlook KitchenAid's version, the Ensemble. After deciding I didn't want to wait for Miele's rumored forthcoming 8 Kg machine (I inquired about it and they never e-mailed me back), I bought a new Ensemble pair. They replaced a 3 year-old KA Superba TL set, exactly like the washer Geoff just bought (see thread #7395). So far I absolutely love my Ensembles. The washer is incredibly stable when spinning, more so than the KitchenAid TL it replaced, as well as the Bosch FL before that. My laundry room is on the second floor, and there was a marked floor vibration with the other machines, but not so with the Ensemble. Yay!
I chose the Ensemble over the Duets and Kenmores because of price and warranty. The appliance dealer I frequent gave me a great deal on the set. The washer alone was about $150 less than the closest equivalent Kenmore model, and about $100 less than a Duet 9400. The dryer was less than its sister brands as well. KA also has a 2 year warranty, compared to the other brands' 1 year warranty.
