SpyFu.com is a pretty nice tool to check who competes with whom on paid search with what keywords. It also tries to guess CPC and daily ad budget for a domain or keyword.

Here are the two articles trying to make sense of SpyFu's magic:

• 4 Ways to Fool Your Competitors Using SpyFu
• The Small (but Great) SpyFu Experiment

My guess is that SpyFu probably uses Google AdWords Traffic Estimator to get CPC, daily click volume, ad position estimates and do some estimation on daily ad budget.
