I just broke down and picked one up too. Really wanted a welder, but so far playing with this thing has been fun. I took one snapshot of the wife sitting on the couch with the flash sitting 45 degrees off her bouncing off the ceiling. I had no regrets then. It's night and day between using this (remote or hotshoe) and the onboard flash.
I couldn't sleep tonight so I got up and been playing with it since.
