I like the bracket by sw motech because it is easily removed. Maybe I wouldn't ever remove the bracket, but it sounds cool to have that option. As far as boxes I like the look of the touratech and the givi Trekker.
There is a guy local to me that makes boxes in his Shop. They are priced about half of the others. He doesn't have a web site but you can find him on Facebook at solobox.
I've got to save up for a while, so I have plenty of time to decide. First on my list is a taller windshield and an improved seat.
