I am also internet and self taught (only a 1/2 hour lesson with a pro to tell me what I already knew - overswing, overswing, overswing).
I joined an indoor winter facility with a video camera. The reason why I was posed the question; was that other guys at the facility are essentially practicing on camera ... hit a few balls ... tape and review a swing ... hit a few more balls ... tape and review another swing ... and repeat for an hour or more. Hmmmm, why does this sound like LP's dream practice session?
I have forced myself to video once a week, and the rest of the time I spend there is working on what I was doing wrong in the last video ... overswing (see a pattern yet).
Since most of my time spend is working on one thing in my swing, I am finding that I am able to diagnose my swing ... take a swing on camera and know what was wrong or right before reviewing the video ... which has been a surprise to me. I was just curious about who else is doing this.

PS - LP if I was to get my driver reshafted I would probably go with one of the LD versions of the Assassin (if I stayed with Accuflex).
