I went with SW Motech, but confess it is not bolted on yet.. I already have their pannier-mounting system w/quick release, and their crash bars, as did my KLR.
Other than their instructions SUCK, I typically go to Motech first. I can make out "Actung, Achtung" and then I am in the dark.
That being said, the ones suggested above are a smart looking product as well, and I normally prefer to spend money that goes to the smaller operator, but I got a bunch of Motech stuff all at one time, and knew it would all work together for my application.
