Thanks dragonette! Yeah I paid $189 for the lamp tree and yes it screws into the back of the stand. As far as making something similar goes, I would say it is definitely feasible. However, it would take quite a lot of work to get it to turn out as nice as the lamp tree. Mainly because of the adjustable height feature. It really depend on how prepared you are to work with metal. I dont have a welder or the equipment necessary to easily make one. Its all up to you. I did think about trying to make one, but it would have taken me all weekend, cost me $70, and it probably wouldn't have come out as nice as the lamptree, so I just decided to bit the bullet and buy it. Anyway, sorry for the wordy reply...haha...you could alwasy make something out of wood as well.
