Complete DVD Set - Bonus Features

I was looking at the complete DVD set and there are a ton of new bonus features on it. I'm not sure I really want to spend that much money on the full set just for the extra bonus features. Does anyone know if the Karen Grassle or Katherine MacGregor interviews are on youtube or anywhere else? I've found some interviews like Richard Bull's and Matthew and Patrick Labyorteaux's but can't find Karen's or Katherine's. Has anyone seen them? Was there any interesting info in these interviews? Thanks for your help!
