AdWords Bid Simulator

Google is rolling-out a new tool that allows you to see what kind of results your bids will likely get you.  The data you get includes the estimated position your ad will be in, the estimated number of clicks, and the estimated number of impressions you will receive for different bid amounts.

There are a number of stories about this at:
