I'm slowly setting up a Strobist kit and I want to go wireless. Pocket Wizards are out of the equation at this time. Radio Popper Jr sound really good but there are still many unanswered questions about them. The SkyPorts are interesting but I find them a bit expensive for what they do so I'm looking more and more into the eBay triggers. I don't mind getting my hands dirty and moding them to obtain better performance/range out of them. There are many sites that provide solutions for their shortcomings and I feel they will provide what I'm looking for for a fair amount of money. With all that said, should I be looking for the 4 or 16 channel models ? I don't see when I would need more than 4 channels so it's probably what I'll buy but what about reliability and performance. Are the 16 channel triggers better in those departments ? Any other comments on why I should choose the 16 channel triggers over the 4 ones ?
