So, I have been contemplating getting a hotshoe flash for my Nikon D90, and I have been trying to find one that is affordable but will give me enough features to really start expanding my range of shots. I have been looking at the Nikon Speedlight SB series, and I have been leaning towards the SB 600, since it's quite a bit lower in price, and it still offers some interesting features like remote mounting and other controls along with having an incredibly high user rating. Does anyone here have one or have input on another flash to consider? This is a totally new arena for me, so I want to be sure to put my right foot forward. Thanks!
