I absolutely love the Argo but would caution to make sure your bike plays nicely with it before committing to purchase. Argo claims it should work with Aluminum bikes but I would be very wary of that combination, most AL bikes are near the edge of their engineering parameters and the Argo loads the frame in ways that I'm not 100% comfortable with. If I were to use one - almost bought it but then settled on a 2nd hand Christiania - I'd use it on a steel bike, not an aluminum one. (The bike it was supposed to go on was an aluminum one and that is why we ended up abandoning the Argo.)
