I agree that OTT is too expensive. The bulbs are nice however the rest of the components fall apart far too easily. I have one OTT lamp, and it is okay. I would not be happy with it however if I had spent over $20. It was door buster special at Joann's.
Not long ago I added two more florescent lamps that I found at Ikea for $20 which are a better IMO and I LOVE them. The Arm as well as the Head are adjustable. Since the head rotates and swivels, which my OTT does not, I can pull the arm down, rotate the head and point it right into the bobbin area when cleaning there. I love that it clamps to my table and therefore doesn't use up any space on the table top.
Here's a link to the type I got:
