I made my buying decisson based upon this thread, with quality, durability, and overall width a fairly big factor for me. Price was not a factor for me.
I bought the 8" Jesse's (sarfari) with inside liner bags. Installation went smooth and the fit was pretty impressive.
One minor inconvienance is you have to drill and mount the strap hooks yourself.
The gas cap is *very* close to the bag and you have to "tilt" the bag when opening the gas cap.
Since the bags are higher than the seat, if you have a passenger the bags will cut into thier legs, on long rides with a passenger I expect this to be a problem without a solution.
Both the mounts and the bags are well made. Taking the bags on and off is pretty easy.
