Mandriva Free Downloads
While true that Mandriva does have Commercial & Corporate packs for sale they also maintain free editions for download from over a hundred mirrors.
Goto "Download from public FTP mirrors".
edit- What's wrong with Distros that sell their products? No one ever said that open-source meant free. There are literally hundreds of Distros to choose from. A few enterprising companies will not hurt Linux in any way, in fact it helps Linux.
