Pocket wizard is a brand, they carry several products so its helpful to be clear which product you mean. As mentioned above those flashes have to be controlled at the head, but at roughly 1/6 the price you have to ask how much convenience is worth.
Sorry, I meant PocketWizard Plus iii's. This weekend I'm going to run through the gear guide that Elv posted (Thanks, on first glance its very helpful) and really think about my requirements, and go from there. I believe convenience will justify the extra cost for myself personally. I will be less inclined to take along all my flash gear the more involved the setup becomes.
