I just bought 2 canon 580ex II speedlite flash's on eBay last night. Now I am looking for a reliable wireless trigger system for them. Ideally I would like to keep one flash mounted in the camera while shooting with the second wireless. With plan in the future of getting a third flash. I looked at pocket wizard trigger systems but read a lot of bad reviews about interruption while using canon speedlites. Is there any other wireless triggers the are pretty reliable? I have been recommended phottix oden wireless trigger but then I won't have the flash mounted on camera like I would like. Also keep in mind it might not always be in plain site. Might need to trigger threw a small wall. Any recommendations would be appreciated. Was thinking about ordering a cowboy studios wireless trigger system on amazon for like 30$ to see how it works but am thinking it will just break or not work right being so cheap.
