Yongnuo Speedlight with D5100
I'm new to using flashes; I just purchased the D5100 about six months ago as my first DSLR. I'm looking at getting the Yongnuo YN-560 speed light ( http://www.amazon.com/Yongnuo-YN-560-Speedlight-Flash-Canon/dp/B004GZLFHM/ref=sr_1_1?ie=UTF8&qid=1324262865&sr=8-1 ).
I noticed today that they just came out with the YN-565 speed light for Nikon as well (Not on Amazon yet, http://www.lightingrumours.com/yongnuo-yn-565ex-for-nikon-released-1667 ).
Can someone tell me the major differences between these two flashes, and whether you'd advise one over the other for a beginner with flashes?
