I have a Blackburn Mtn Rack, pretty much bomb proof, and cheap. Tubus are nice, another option could be NITTO or Surly if they still make that rack. Personally I like NITTO, If i were going to buy new racks. I have a waterproof pannier from NASHBAR it's good enough for commutes for me. Came across these other day,
