These results show, considering they are about 2 years worth of continuous searching, that in the end it doesn't really matter where you look. You will find typewriters worth keeping in just about any venue as long as you keep at it long enough! Perhaps the antique store findings would be much higher if I had allowed myself a limit of, say, $50 instead of $30. But only slightly.

And well, actually, it's Lynnwood and Edmonds but Seattle sounds better.
