Anyway, check out http://animationbuffet.blogspot.com which also has a couple of handy categories to filter out what you're looking for, be it cartoony rigs, creatures, females or whatever. There's a good few to experiment with, and seeing as the guy tests each one himself, it seems to be a good call. It's also linked from www.11secondclub.com which is also a trusty sign.
Speaking of which, this month's 11 second club clip seems pretty good, so time allowing I shall be having a bash at this. Haven't decided what rig yet, but said website is a good place to look.
Anyway, I am busy busy and had severe lack of internet, hence the declining posts. But I shall be sure to post new stuff or anything helpful.
