theyre just over $100 for a trans/receiver Cyber Sync (you can get 10% off for being a student!) vs nearly $400 for the Pocket Wizard. youre fooling yourself if you think spending more gets you a superior product. both of these items are made of monumentally cheap electronics. you need pocket wizards if: keep in mind also, that CS's are rated at 350', and PW are rated at 400'. so theres really not much of a difference. with repeater mode you can double the CS's range. end of story. sticky?
