Turbosquid. It's updated daily but lots of things you must pay to download. About one third of the files are free. The only thing though, if you want to download a file, you must first register, which doesn't cost anything. There are some pretty good models there. Check it out.
Along with 3D Studio Max stuff, it also includes files for Poser, Light Wave, Gmax, Cinema 4D, Shockwave 3D, Softimage, and Maya.
