New Trek 520's are selling new for over $1000.00. I doubt very seriously you'll be able to pick it up for much less than 500.00. If you can, grab it in a hurry. I've got one. They are super touring bikes, but in my opinion, unless it's already been done, you'll want to change out the gearing. Even today, they still come new with gearing that is a little on the high side for serious touring.
