A friend asked me what flash to get for use with the T3i but didn't specify what kind of photography she plans to use it for so I'm going to say "general". My thought is it depends on how much you want to spend and how much distance you need but I'd like to know if there are any amongst Canon's current offerings ranging from the Speedlight 90x up to the 600EX-Rt that Canon users here would specifically recommend against. Thanks for your input.
