Here is a low cost alternative. The cup holder cost $6 and the short mount studs were free (well, a couple of minutes time to cut, drill and tap some scrap aluminum). I used 1" stock, but I might turn them down to 7/8" to make them work with more accessories. Cup holder seems to work alright. More miles will tell the tale. If it doesn't work out, I am not loosing any sleep over it.
