I actually slightly disagree with you for once AsherF.
joeymagicfreak you seem to be quite interested in many of Paul Harris' products, therefore AsherF recommended you get Paul's extensive and amazing materials Art of Astonishment and True Astonishment DVD set. Both of these are quite pricey (at least for me), so if you have never tried Paul Harris' material, you should get one of his more inexpensive products and see how you like his way of thinking. After the initial "taster", you can decide whether or not to buy more of his stuff or the other products on your list.
As for me, I would recommend you only get one product out of those you listed, and work hard at perfecting it. Even if you dislike it, don't throw it away or hide it in a back drawer; think about it, digest it, try to make it yours. You bought it in the first place -- why give up?
If you love it after you buy it, cheers for you!
Good luck.
