I am interested in purchasing a few accessories for my nikon d70. However i am still new to photography and want some input on the best to get. First off I want to get a remote so i can release the shutter while its on a tripod. After looking around there are several remotes available. Which is the best for what i need? Nothing special just shutter release from a small distance. I also want to purchase a better flash. I have looked at the SB-600 and SB-800 and i belive these are the way to go. What im wondering is what is the difference between the two and is it worth spending the extra 100?
