Lets say you scrape your pennies together to get a camera kit (D40, Rebel XS, A-200, whatever you use). And then you get a couple of hundred bucks. You can either get the zoom telephoto lens (55-200) or you can get a separate flash, and try and become a "strobist." Which would you rather do? I know this decision is unique for everyone depending on what they like, but I want to hear people's opinions.
