Are any of this lot worth a look ?

Rich Dimitry's stuff is very good.
So is Marc Macyoung.
I find Tony Blauers material is useful. I trained with him for a little over 3 years and have several of his tapes. His only drawback is he tends to get overly technical and repetetive to waste space on his videos. Also he talks just for the sake of talking and making himself feel important. I wouldn't bother training with him in person, but some of his vids are good. Try the Take it to the Streets video.
Richard Dimitry's Shredder vid is amazing. Read Marc Macyoung's website for tons of info.
