I was at the Burien Salvation Army today (Burien is west of SEA-TAC Airport) and they had an old Maytage washer (center dial, push buttons, and I think a lighted backsplash) as well as a pretty cool Kenmore Dryer from probably the 60's.
I wish I could be more descriptive, but I had just been to the eye doctor, and couldn't see very much detail on stuff. But if you're in the area it's worth checking out.
