Yep, they is pricey but then again so are the plastics. It's all what you want, of course. I think the protectors from Top Block integrate the best with the style of the bike. Can't say how well they work. I, on the other hand, use the GSG frame sliders with the MC Enterprise short rears to protect the cases. They're black and blend somewhat into the bike's lines. Can't say how well they work either. Haven't had an incident with them.
