I used to skim. Now I use this ..... http://www.lnt.com/product/index.jsp...separator&sr=1

Actually on Friday eve. I made some chicken stock and used it. When it's ready, just pour and it separates well in a few seconds and it's pretty effective. I think I made about 4 quarts. I have the bigger one and I had to do it several times but it's worth it. I hardly detected any beads of fat floating.
