I tried finding some previous flash posts, to not make everyone repeat themselves, but just decided to ask a new one. I've got the D80, of course my on camera flash is no good. I'm doing a few wedding for friends this summer. So I would like to hear your opinions on which would be best for this. I realize that to get proffessional quality I would need to invest much more money in equipment, but for now that is not an option. I have my D80, probably my 18 135, a backup friend on a Canon S2 and hopefully some sort of extra light source. Price range around 300 preferably, but open to any suggestions. Thanks!
