Character models.

Does anyone know where I can get some solid character models for GMod, instead of ragdolls or NPC’s?

just uh statue the ragdolls?

For some reason anything I spawn from L4D2/TF2 disappears after about 5 seconds…

This is basically what I’m looking for, but haven’t found anything remotely similar looking around various sites >:
