I have a few hundred dollars i want to spend on a good 3d modeling and animation program. Any suggestions? I'd say about 100-300$ would be good. Please, I am looking for something with a good looking interface and stable website.

XSI Foundation is going to be your best bet, but I think the pricetag is closer to 4-500, iirc. On a nicer note, however, is the fact that you can use XSI Mod Tool for free while you make your decision. It has pretty much all the functionality you will need. Consider it a free trial of the full version.
