Another route that has developed, is picking up the free version of SketchUp v.7, and the plugin from this Japanese site:
---------------------(quoting from a poster at DAZ)-----------
"The Ruby Export script I used for this came from here. The site is in Japanese but just download the su2objmtl2.zip file. There is a lot in there but the file named su2objmtl.rb is the only one you need. Go to where you installed Sketchup and place it inside "..GoogleGoogle SketchUp 7Tools" and you should be good to go. When you run Sketchup it will appear in the plugins menu.  

---

This will give you access not only to those models which are only available in .skp format, but also the .dae models which don't work right under D/Studio (usually because the sub-objects are in .skp form....)
