"KK" is Kadey-Krogen, the builder. The 48 dhays linked to is the latest model. There are actually two for sale up here, one in Seattle, a 2006 for $675K and a 2001 In Friday Harbor, for about $640K. I can't say enough good things about KK or the people in the company, but I am biased as we own one. But, you could not ask for more from a builder.
