Ive come across these panniers from SW Motech on the web, i havent seen them in the "flesh" as such. A choice of finishes and they dont seem to be very expensive. Regards mounting the boxes, i personally would go with a Hepco and Becker pannier rails and the Touratech mounting kit
On the site it says 16 week waiting time.
