I'm guessing you're looking for a new-from-a-store answer, but seriously the best Washer/Dryer combo from a mustachian standpoint is to search CL.
Almost new Washer/Dryers are two items that routinely pop up on CL for less than half of new. It seems to be a function of people moving / combining households and how big/clunky they are, which results in there being a surplus available only to people within driving distance. We picked up our last set (a front-loading GE about 3 years old + matching dryer) for $400 when the equivalent pair was >$1,000 at Home Depot. Five years later they we haven't had a single issue with either.
