Just an idea at this stage, but I'm looking into buying one.
I don't know that much about them so could someone tell me a reason why I should go for a new "Canon Speedlite 580EX TTL Shoe Mount Flash" for around $700 rather than a 2nd hand "E-TTl Speedlite 380ex" for around $200?
Will I notice a major difference in quality or usability?
