A few of us members here do. But to the best of my knowledge, no one has one with the liquid wax. And, I haven't seen a pic here from any member that looks like that one.
Right now, we're working on putting Jonas' entire Lava Lite history in our Lava Library! :) Check out the decade sections under Lava Lite History:
