Hey,
I have a canon 20d and 430 ex. I have found myself limited by on camera flash at this point. I would like to be able trigger it wirelessly. I have looked at the canon offerings and from what i have read there are line of site issues. Pocket wizards are an option but i would like to keep the price down if possible. I found these speedotron ones http://www.adorama.com/SZ23492.html but dont know much about them or what else i need. . I have used the search tool and found some helpful information but nothing to help me make an educated decision. I will be using the setup i get for anything from cycling photography to portrait and landscape. Any input would be awesome.
