i want to buy a good flash unit for my dynax5 body, which do you suggest? please consider that: - i found a used 5400hs for 228euro - a new 3600hs costs 230euro - a new metz 54 mz3 costs 319+59 for the sca (seems too much for my wallet) - a new 5600hs costs 430euro (really too much for me) - i'll consider sigma, soligor, nissin or whatelse if you have good experience with it and it costs less than a 3600hs I don't have any flash experience but i suppose: - i'd need swivel - i'd need wireless - i'll need high speed synch please help thanks in advance
