Anyone used content packs from Frogames.net?

I am at the point where I need a little better art for my app and am wondering if anyone had tried to make any .egg files from the content packs sold on frogames.net/content-packs.html ?

I am really interested in a player model with more animations. I might just buy the proto pack and test it myself.

Can anyone recommend another place to get some well animated models for use in panda?
