I just stumbled upon this link:
http://www.infinitee-designs.com/Free-Maya-Models.htm

It is a page of freebie models in both OBJ & Maya formats. There are some nice looking obj clothing there, that should make nice dynamic cloth for Poser; also a couple of spacecraft, and a VERYHIGHPOLY 1970 Mustang Mach1.

{I haven't tried anything from there yet; but I didn't want to forget to post the link here.}

Thanks for the link my friend!           

The Mustang is a MUST-HAVE !! !! The other objects are very interesting too ! The dynamic dresses are very beautiful ! I'm always in search for some of them   !!
