Guily Gear Tutorials

[Blaine]

I'm thinking of taking up Guilty Gear since it's been a while the last time I really sat down and learned a fighter (Mark of the Wolves and, to a lesser extent, Last Blade 2). I have Guilty Gear X for the Dreamcast and got Guilty Gear XX AC for the Wii - to go along with my Wii Fighting Stick.

Can anyone suggest some good tutorials or guide materials for the GG fighting system?
