I have mine through USAA. I don't recall exactly how much I pay for it, but I know it's not a ton (actually it's cheap enough that I don't think about it). I also have our renter's & auto insurance through them as well, and we've been pleased with the service/pricing.
I can't find it now, but I remember reading about this guy a while back, and it stated that he did much of the effects in camera. Just wanted to throw that out there in case it changes your perspective at all about what he's doing.
I was pretty close to pulling the trigger on a set of PocketWizards to use with my two 430EX IIs and my 530EX II, but instead went with the Yongnuo YN-622C, and I love them. I haven't had any misfires with them, and they support wireless TTL. I'm really happy that I didn't spend the extra money on the PW setup.
