True, if you went with the varios you would need to swap out the mounts, but you can put Varios on an Adventure. Then you would be able to sell the rear side racks for $300-350 and buy the Vario mounts for less than $100. You could probably buy a decent set of Varios and Mounts for $600 or so. BMW racks are usually a quick sell in the flea market here.
On another note, if you're interested in selling the rear rack for the top case I would be interested. In fact I will be passing through Nashville later this week and can pick them up and save you having to ship them. PM me if interested.
