Just thought I'd post an update - after presenting the options to his wife, she decided to go with the K-x, largely because we could still get it new, and if he had any problems it would be covered under Pentax's warranty. We ordered it, and it should arrive at my house (where he'll be in no danger of stumbling across it between now and X-mas) in a couple of days. At which time, I plan to pull it out of the box and take a look in person at how it compares (controls, size, etc) w/my K20D.
I'm still waffling about picking up a K-x myself specifically for vacations and travel, because it's lighter...IDK.
Bob - my friend is actually in Seattle, but it's pretty amazing how often their weather matches ours, and the scenery is pretty similar, too.
Whereabouts in Oregon are you? I'm in Albany, about an hour and a half south of Portland.
