Bob - 1961 on the Nutone? I would have thought earlier but I don't know much about them and the house seemed older than that, but after 6 sales, they all look alike! The model tag on the Nutone calls it an "In-Built" ;-)
The Sunbeam I'll probably use at some point, it looks very fun and with the light, I won't need additional under-cabinet lighting.
The Maytag as taken many hours of work but it just sparkles! I didn't get it tested last night, had to watch my stories on HBO and the final episode of Queer As Folk on Showtime. Tonight for sure!
