Hi, I just noticed the V4 version of the Cactus wireless triggers. I know a lot of people mod their V2s to get crazy distance, but the V4 looks to be good for 100ft out of the box, it's smaller, and can stand up on its own. Anyone using these? Any feedback on them? I am evaluating my options on triggers. PocketWizards (New ones) will run me $400 and I am noit sure I need that much for now. These may be a good solution for me at the moment.
