I currently have a D90 and want to get another camera. I want to upgrade and looking at a few different options. Would love to get a d300s, but the cost is a factor at this time. I found a D200 with 26K actuation count mainly used as a back up and in studio type work for $700 and comes with the Nikon Extended Battery Grip with two batteries. I am new into photography and learning everyday. Should I get the D200 or wait to I can afford the d300S?
