Stock Photo Sites

There is a gazillion stock photo sites out there… I am trying to find the best one either to subscribe to or whatever. You got ones that make you license individual images for like 800 bucks, and other ones that you subscribe to for like 100 bucks a month…

I was wondering if anyone has been down the road of seeking the best stock photography site and who recommends what? I don’t need licensed images, I need good ol’ stock photos I can use as backgrounds and in collages and other stuff.

any ideas?
