and on that note, don't get an 18-270. ever. Would be a terrible lens. The best Nikon kit lens is the 17-70 f3.5-f4.5. I'd actually say it's a step up from what other kit lenses are - since it's way sharper, and doesn't have as variable of aperture. Get one of these for starters if you're not going to just go with the 18-55 basic lens - but never, and I mean, NEVER go for a 'super zoom' (basically any lens that goes from a wide end of 18ish, all the way to 135mm or more) because they are all basically a waste of space and weight.
also, what are you shooting? if it's just video, you don't need a dslr. You have plenty of other options that you can look into. If you want at least 50/50 between shooting photos and video, then you're in the right area.
Honestly, I don't like Nikon's cameras for video at all - but that's just me. I just never have felt they are as tailored to video use as that of Canon's stuff (basically, there are some annoying things, like having to stop recording just to change a simple setting - I can't waste my time with that shit - the quality is just as good, though) You also can't adapt old lenses very well to nikon cameras. Even old Nikon lenses work better on a 4 year old T2i using an adapter than they would a lot of the Nikons.
for just photography, it doesn't matter which way you go - canon or nikon or sony or pentax - they're all awesome systems.
