Which site do you use to track your stocks?

[LuckyTaxi]

I just signed up for sharebuilder and while it would make more sense to use it's builtin portfolio, I am more keen to yahoo's finance page. For those that invest, which site do you use? I've tried google and msn but yahoo's portal seems to be much quicker. Google doesnt supply much info in regards to the company and industry of your stocks.
