Anyone else frusturated by the lack of decent biographies?

Why is it that there are so few good, in depth biographies on Jim Henson? I've read Jim Henson: The Works, which talks less about his life and more about his work. Even so, that's the best one I've found so far. :/

It might be a good thing because frankly there's very few biographies that I've ever been satisified with. They're badly sourced or badly written or there's nothing new.
