Favourite Homebrew (and 3rd party) Classes?

I'm a fan of adding more classes to 4e to fit in niches. I've already given my players the option of using Chris24601's Essentials Options article, and I'm interested in any other good homebrew classes you can recommend, especially ones that include powers to level 30, or Elemental and Shadow power sources.

Edit: I'm also interested in classes that have been published by 3rd party companies, if you have any to recommend.

My house uses the art of extreme reflavoring so the inclination to homebrew classes didn't seem important (but I am sure others do)

We haven't played enough 4E campaigns to let everyone play the standard classes they'd like to play yet. So we haven't really had a need to brew up any new/different stuff. And we also do a lot of re-skinning to make the existing class match more with our expectations.

I am interested in the 4E version of the Incarnum classes from 3.5 (can't remember the source book right now). I have a PDF that someone had made for the class. I was considering seeing if I could get it in to the offline CB and build a character from that. But, I'm not very handy with coding, so I don't know how tough it would be. Plus I don't know that any of my players would be interested in that anyway...
