Rigged Model?

Hello and i want to teach me character animations.

I once did a walk cycle that looked okay but then forgot how to animate sinse blenders interface changed due to blender 2.5.

So i am really glad if you guys send a good link to a good rigged character for animations.
also a tutorial on how to do a walk/run cycle

i have some experience with the armatures
thanks

what style? cartoon? realistic? Blendswap has tons.

Ehm… i am looking for a realistic character rig and i checked blendswap and did not find anything good D:
