I bought the DS tool box for my S10, but it is fitted with OEM panniers (which I actually like!).
Fitted it with little trouble, but the bracket at the front seems marginally too short. Still to see if it stays waterproof.
However I bought mine from
http://www.newstylemotorcycleadventureaccessories.com/ and Richard who I dealt with was extremely helpful. Any come back is with him rather than DS direct, and he is based in UK. Don't imagine him being anything other than as helpful as he was with my order.
