i really want to get a flash but in no way can i raise the money for a sb600 now or in the near future. so i was looking at this flash here. now i know it wont be as strong but is it a good flash? now i see that the metz only has vertical tilt so what about this one? here its the nissin di622 now i dont want someone to tell me the technicalities of the flashes just if someone had some experience with either of them... are they good?
