We have the Duet set as well. I dont overload it though, sometimes it seems to leave some of the stains in. On the plus side, the clothes are almost dry when you take them out. The dryer is the most amazing thing I have seen, it drys in no time.
I researched the LG too, they had much better reviews than any other, but we found the Duets at a scratch and dent place for 290 for the dryer with the pedastil and it was 560 for the washer with the pedastil (sp).
There is a place by me called Appliance Liquidaters they are the cheapest around, and they just turned an Appliance direct into a Scratch and dent world over by me, if you call them they will check and see if they have the one your looking for and if they dont, they will call you when one comes in. Hope that helps. Good luck!
