I second this, both the book and DVD are definitely worth owning and using. They can be a huge help.

It's chock-o-block full of great stretching and accuracy drills. And Holdsworth's Reaching For The Uncommon Chord is a great book for stretching (literally and figuratively) your chord shapes in new directions.
