The Raleigh and the Trek look great... another thing I would check is to see what size tyres you can run as in the PDX winter you may want to run a CX tyre or pick up a second front wheel at some point and mount a studded tyre for those rare days when Portland does get ice and snow.

Skinny tyres are not automatically faster and when you are commuting a wider tyre will improve the ride, reduce flats, and allow you to cross urban obstacles like the trolley tracks.

Portland streets are as bad as ours and when I am there I bomb around on a Raleigh 20 with 20 by 1.5 Marathons while my wife rides a Breezer with 26 inch Marathon tyres and on this bike you can forget about the roads.

Up here I prefer a 26 inch wheel for commuting and touring... with this I can run tyres in the 2.1 - 2-3 width on some bikes but can also run very fast rolling 26 inch slicks and everything in between.

My XC / monstercross / urban assault vehicle runs 26 by 2.0 semi slicks and will go through nearly anything and do it at some really great speeds... have not flatted once in over 10,000 km of using these tyres.
