Although it is a it late for he original poster, I will throw in a comment for anyone else looking for suggestions.

About the time this thread was created I ordered the Green Guru pannier from Amazon. The picture on Amazon didn't match the Pannier on he Green Guru website, but I ended up getting the style pictured on the Green Guru site, which is what I was hoping for. It is a good pannier so far. Plenty of space for commuting with clothes, shoes, and a jacket. However, the lower hook that connects to the rack isn't the most secure. It is a hook connected with an adjustable elastic band. This allows the bag to wobble a bit and during one ride it did manage to unhook from one of the top hangers. I'm guessing the lower elastic wasn't tight enough or came loose. I still like the bag. The stitching is good and it appears that it will last a long time. Being able to mount a blinkie on it was a feature I really wanted too. I have it on an Ibera Touring Carrier Plus rack.
