A friend that I toured with in Ohio this past fall had recently purchased a Chinese knock off pair of yellow Ortlieb-like panniers. They looked similar but the material was not as thick or heavy duty as the Orts. Also they had a similar attachment method but the plastic hook(s) was not as heavy and flexed more. They seemed to work for him OK on their maiden tour but only time will tell how they will hold up. If you're really interested, I can find out the name and where he purchased them thru.
