Rank Checker... pretty cool
searchenginereports(.)net
You enter your URL, the enter the keywords you'd like to check to see if your domain ranks in Google, Yahoo or Bing.
I don't know how far it looks... maybe it stops at 100. And I don't think its entirely accurate because I did a manual check of one of my sites/keywords and I was #1, but this tool didn't list me at all.
Anyway... its a cool tool in case you are curious to see how your site ranks for any particular keyword.
Only dead fish go with the flow.
