The best place to find Product Connect compatible 3D product models is in the Google 3D Warehouse. We've started a Product Connect collection that you can find here: http://sketchup.google.com/3dwarehouse/cldetails?mid=e4c5f9469b0b38abb7dc65d7950bd55b&prevstart=0
We have already worked with a number of manufacturers that have begun loading compatible models and tagging them for inclusion into this collection. Look for thousands of models to continue to be uploaded and added to this collection in the coming weeks (and hopefully many more into the future).
