$150 is right, it's a nice frame and for touring, it has some advantages: Bar end shifting, has eyelets, clearance, and good geometry. Weight is not really an issue, and it's a steel lugged frame that even the Miyata 1000'ers and Expeditionites will smile and say nice things about. The 27" wheels are smooth, and the hubs and all bearings can be cleaned and repacked to silky smoothness. Parts are cheap and readily available for the drivetrain, and it's easy to work on. And it's a Centurion, instant cred.
