TAM: The Animator's Modeler

This looks pretty cool! Customize your own rig, then export it as an OBJ, FBX or MA file. The app is $25 and you get two rig exports with that. If you want more you have these pricing options:

1 additional export             $11.99

3 additional exports           $29.99

5 additional exports           $39.99

15 additional exports         $49.99

25 additional exports         $59.99

If you grab the $60 one that's around $2.4 per rig! Not bad!
