As far i can see 80% of the models are freely downloadable... http://deino3330.blog85.fc2.com/
.
and then click on the link that lead to the dlsite.net site.
once there, there's a tiny little button to download the mmd model.
Probably there's more to grab on dlsite.net than deino's items...get to check that.
Have fun.
if someone want to make a 'pack/bundle' of it all...
