There are so many kinds of bedding - which one is the best? And what kind do you use?

I know that cedar is toxic, so I never buy it, but what about pine? Some people say that all pine is toxic, some people say that certain kinds of pine are okay, and some people say that all kinds of pine are good. I'm confused.

I usually use aspen. It's fairly absorbant, not too expensive, and makes their cage look bright (unlike the carefresh I used to use. but carefresh is good too, just expensive.)
