It's.... Ummm.... Well, free. At least for us, anyway. I imagine he's paying the cost for the bandwidth he chewed up from everyone downloading.
I guess I can see why you'd be disappointed with the models he chose, but he did mention that he did not spend much time selecting them, and that some may not be the cutting edge of what is out there. But he still took the time to do all this, and he included a smaller, non-model version. He also took the time to tell everyone how to put in thier own models if they were not pleased with those he included.
I, for one, am grateful he took the time to do all this in the first place.
