+1 for TAL stuff. I use their plugins and it's pretty great. Also cheers Labrat for recommending Noisemaker, I had it on my hard drive but never bothered to use it until recently
I want to add one plugin that I think deserves a lot of love because of how good it sounds.

This is probably the best freeware chorus plugin I've used, ever. It's very versatile, allowing you control all the little elements of it, including an inbuilt eq to shape how you want the wet signal to sound and up to 6 voices. Honestly though, the best part about this plugin is that the software was designed in such a way in which there is very little to no comb filtering at all, meaning that this is the cleanest sounding chorus I've ever used. It's really cool and it's free, so honestly, just check it out!
