You can also go really cheap-A$$ like I did.
Spotted a member here pix (Crazy8ight) who had installed them.
They are smallish compared to some, waterproof they are not (I always use a bag liner for gear I care about).
Sling-over, couple tie-wraps, good to go. They do not interfere with wheel belt etc., don't need bag brackets for these.
Best part $39.95 at Cycle Gear . . . . .
