We bought the plastic flip-up ones shown on the left margin and have been very happy with them. We mounted them low on the transmission tunnel. You might think they would get in the way of your leg but even with a tall drink your knee fits well over the top. Be sure to put them just ahead of the closest seat position used because the seat will tear them up if you don't. The metal ones shown look like they would work well too.
