Just get a shop light from Home Depot or something. Actually I couldn't find them on Home Depot's site for some reason. I found this on Amazon.com, it's almost just like one of the lights I used for my light box attempt. Surely you can scrape together $6.99: http://www.amazon.com/Northern-Indu...0-9820046?ie=UTF8&s=hi&qid=1209442428&sr=1-23
I had the same problem with the blown highlights from too much light coming in on one side with my first attempt. Then I set up 2 lights on my 2nd attempt and you can see the difference. I built basically the same light box as you from strobist.com:
