My great-uncle makes these nifty lamps, they're a fairly simple design, but take more time to make then it looks like. I'll try and snap a photo of one later tonight so you can all see what they look like.
Anyway, he takes one up to the hardware store now and then and has them sell it for him. Being a small town, they have no problem with it, they usually go for about $100, which just about pays for his hardware and time.
You might try that, especially if you live in a smaller town. Ask if they'll sell one on consignment, you might be surprised at how quickly it sells.
