Randy Couture Instructionals: How good are they?

I'm basically looking for some solid instructional material on takedowns and ground control.

It would seem that Randy's instructionals would be a good way to go. Can anyone who has the series tell me about the quality of the dvd's and the material? I have Bas Rutten's Big DVD's of combat, and while I like a lot of the information on there, the section on takedowns isn't comprehensive enough.
