any good hand tutorials?

i’ve been working on a body from a very nice tutorial, when all of the sudden i came upon a link to the hand part of the tutorial, which appears to have up and died a while ago. i’ve been looking for a good tutorial for a while now, and the best i can find is a far less than helpful video tutorial, which did a pretty lame job of explaining the process. if anyone has advice on how to do this, or could give me a more active link, it would be much appreciated.
