Another vote for the Yakima Sidewinder. Very secure rack. Quick & easy to load, but it really is a two-person job (no matter what Yakima says). If you also have Yakima's rack towers, they have their SKS (single key system) available. And along with watching drive-through windows, garages, etc., be aware that you need some separation with a vehicle parked on the same side as the Sidewinder. Some factory roof racks are incompatible with the Sidewinder (car shopping back in '05, and the Saturn's crossbars were the wrong size/shape). FWIW, I've never had an issue with marring of the Speedster's bottom tube.
