great lamp. I assume you meant $50 USD. probably more like 70, but I don't know. I have so many tabs open in chrome that I am afraid to ask google anything.
I agree with the idea of hiding the wires in a groove along the top. You could get a friend with a chainsaw and a fair bit of experience to carve it out, you could use a circular saw if you are really careful, or you could become a whittler and whittle away for about fifty hours.
Be careful of your extremities in each case.

Great lamp btw. if I didn't already say that
