I have tryied all the above and then some... I am currently using CD Mate 2.2.8.1 and it is by far the best.
It is fast, and is ease to use. It has, in short, copied some of the most difficult disks for me where others have produced coasters.
Additionaly, CD Mate has a good site with forum, updates, archives (for copy protection information trouble shooting etc.).
That sayed, nero is a second choise, mostly for ease of use.
