Obviously, the later should be better - but the price difference in a D300 kit is almost 500 dollars, which is quite a bit of dough. No, I don't have any other DSLR lenses, as this is my first one, but what can I say: I happen to have the dough to afford one, and have been known (with worthy events) to take somewhere in the vicinity of 1400 pictures over a 4 day span with my S2 IS, and now photograph concerts for a magazine that you have (as of YET!) never heard of. I'd like to think I'm a quick learner, and do want a camera for which I wouldn't have to buy a replacement for a long, long time. And yet, the 500 dollar price difference makes me a bit queasy. Worth it, IYHO?
