What engines do you use to check your rankings?

Lately I've only been using Google to review my sites rankings. I want to start getting into the habbit of making sure I rank highly on other engines. What engines do you guys check that brings you in good traffic? Is it possible to be high in results for multiple engines for one main keyword?

 

Also would it be better to focus on a different engine than google for once?

 

Google still controls the market, But i'll check them, yahoo, and msn (every blue moon)... Just to see how my site is doing with them.

By focusing on google you basically are focused on every other major SE...

 

I usually check google ranking. I only check msn and yahoo when I see a drop in referals from them.
