What kind of gear do you need? If you mean stuff like pedals, you'll pay a hell of a lot less on CL (or in REI's used section) than if you buy them new at the store. If you mean clothes, give some thought to wool and hiking clothing, 'cause it rains a lot here.
This might be worth test riding if you think you could talk the guy down on price:

You should start a thread in the road forum. I flipped through the bike listing briefly, but there are people in there who make a hobby out of shopping for things they won't buy. People will be all over CL and find you the 10 or 20 best deals in the Seattle area.
