I've been wanting to try P90X or Instanity, but I just could not convince myself to spend over $100 on the DVDs. I just discovered this set today, and Amazon has it for $25!!! Seriously! I think this is something I need to look into, as most of the reviews say it is just as good as P90X and Insanity. So, the production may not be as dramatic and it's not Shaun T, but isn't it really about the exercises and the plan? As a personal trainer in training, I understand it is about the plan itself, and not the production value.
