If you haven't already, download blender 3d (
www.blender3d.org). That's the first order of business. Next is I have to ask what your system specs are because some of the models are massive and slow to a crawl even on my Dual 1.25Ghz G4 PowerMac with 4GB of Ram.
Then All I have to do is send you the models. (Which will be available sometime this week at Blendergalactica.com...I'm waiting for the domain to resolve at this point)
