Re: Recommend good DVDs?
Ikeda's are beautiful.
For technical instruction, step-by-step, Nishio is excellent, and you already mentioned Saito... If you like Saotome's weapons stuff, he's got videos on them. I don't know if the video done by Cool Rain is available in DVD format, but Aikido in Training is also excellent.
For demos, you named some heavy hitters. I've always liked the 50 anniversary DR tape put out by AJ. There's another sold by Julio Toribio that I like for technical analysis. The much maligned Saigo-ha stuff is fun, too. Also, Yang's Chin-na is very interesting coming at it from an aiki background.
