Just to repeat what Spit said, some (actually quite a lot) of the free stuff doesn't allow commercial use. I don't download anything that can't be used for either commerical or noncommercial use. If I pay for it, I know I've bought the license to use it in commercial renders. Sometimes I pay more than I should for a single item. I think some of the artists overcharge for some of their stuff, but if I want it badly enough, I'll spring for it. Melanie
