Guides?

Are there any free sites that have good guides? Or you just have to randomly search through piles of shit to find tid bits of advice, I've been searching around at work for the past couple days and have found like 1 decent rouge guide, and a couple crap ones.
Do you think it would be worth it to pay for one of the membership sites that claim to update every day w/ the new hax, macros, guides and all that other shit?
