Ordered some Tusk Panniers a few days ago, and I'm in the market for a similar top box. Unfortunately Tusk doesn't seem to make one. Any recommendations on a similarly priced aluminum box that is available quick? I've currently got a factory Suzuki plastic box and mount on the back, but it isn't quite big enough and I'd rather have something metal. Have a line on something used, but the seller isn't ready to sell just the one box yet and I don't have a lot of time to wait.
