The have some good tutorials and also some very good podcasts containing news, comments and interviews with professional photographers.
I am currently in the process of selectng new studio lighitng and evaluating constant vs. flash for a three light setup.
Presently I am leaning toward ALZ0's low cost HMI lighting. It's not dimmable but the price is right. HMI appeals to me because I have a couple of halogen lights but don't like the 3200K color tem. or the heat. The HMI is is 5600K and much cooler running.
I would also recommend Ralph Hattersley's book,
Photographic Lighting - Learing To See. He strongly advises starting with constant lighting in order to learn to evaluate the quality of light.
Good Luck!
