I don't know where you can purchase a knockoff, but you can make one yourself out of supplies such as a wooden coat rack, with the arms either sawed off or not attached, (holes filled, sanded, stained), and a drum shade with a bulb rig like the kind they use to hang lights from the ceiling at ikea. You will secure the shade to the post with a slim piece of wood or metal from within the drum. I think it will cost you no more than $100 and have a similar look. Good luck!
