Well you may be right. If you're a professional phoographer who's client is paying ££££'s and relying on you to get a shot then perhaps investing in Pocket Wizards would be a little more sensible.
However, I am a professional photographer, and I have been using the V4's for about 6 months without any problems at all. I just don't get paid enough to invest in the PW.
So in essence go with the wizards if you got money to burn but if you want to try off camera flash you get plenty of bang (or flash) for your buck with the V4's
Incidentally, i've just discovered you can purchase them in the UK now at
