Hey everyone. I've decided that it's time for me to get my hands on some more pedals but I don't quite know anything about each of the different models. I know what kinds of effects I'm looking for, and I'm hoping I can get some advice on what models to try out for each type.

The effects I'm looking for are:
A Wah-Wah (I've seen the original Dunlop Cry-Baby Wah going for a fairly good price)
Some kind of Chorus, Flanger or Phaser
An Octaver

What brands and models would you recommend for each of those types?
