Given your height/weight and budget, I would like to suggest a Rodriguez Rainier. It seems to fit the bill just right with all your requirements. You can get a nicely specd one with top quality 725 Reynolds steel and carbon fork all within your budget. Based in Seattle, these guys have lots of expertise in touring, randonneuring and tandem bikes. With 18 production sizes, your bike will be virtually custom which will insure a perfect fit.

Edit: I see one of your choices is the LHT Disc Trucker. If you want disc brakes (Avid BB7), they will also work with you, but use a steel fork instead of carbon.
