I paid 35 for one that was complete bottom, and 15 for just the legs and one bracket between the legs. I think the 80 is over priced. It is pretty though.
My DH made me a lamp table for my sewing room with the base I bought. The table is then the same height of the machines I have there in cabinets. I won an Ott light in a drawing from a LQS celebrating their aniversary in business that needed a table.
