Take a look at this free keyword research tool I just heard about

Hello Visitors, talk about something extremely cool that I just discovered... Internet Marketing guru, Brad Callen, just told me about a free keyword tool that they recently created. The tool allows you to see what any Adwords advertiser is currently bidding on via Google Adwords! And what's even cooler about it is how it works. All you have to do is browse Google, and the software will automatically place a "view keywords" button below any Adwords advertiser's listing. If you click the button, up will popup a window that shows you the keywords they're bidding on! It's super cool. It does a whole lot more, but I'll let you play with it yourself. Here's the link where you can download it for free:
