A friend on OH sent me a vitamin comparison sheet that compares all of the major multi-vitamins in excel.
I created a folder for us on google docs and put it in there: https://docs.google.com/leaf?id=0BwPC9d3CCc0WNjAxZjM2MjYtYjJhOS00Y2YyLWE3ZmEtNjJiZTU5ZDc2YTM1&hl=en
hope you find this helpful in making vitamin decisions.
Let me know if you can't open this.
