i dont know if this has been already posted, or if you guys already know this, but a friend sent me a link to this youtube channel that has just under 200 commentaries in english. (he does it over the korean ones). he is very enthusiastic, and might be a bit hard to understand, since he talks extremely fast.
YouTube - KlazartSC's Videos (http://www.youtube.com/profile_videos?p=r&user=KlazartSC&page=10)

It's funny because his jokes are really lame but he bags the guys out for having the names "The Zerg" and "Zerg Boy" in one of the videos.
