Lighting Ideas

I'm hoping people will share what types of lighting they use in their photos. I have a Canon Rebel XT, but I cannot afford a special flash right now.  Are there inexpensive methods (under $100) to create good lighting for my photo shoots?  I love pictures of lizards on white backgrounds, but when I try to take those, I always get shadows.  Suggestions?

Check on Ebay for a light tent. Good way to diffuse the light so that it isn't overexposed on a white background and also helps alleviate shadows.
