Thanks for all the input.
So yeah, I wasn't really interested in an 18-200, I don't need THAT much zoom, but something a little more than 55 was more what I was thinking. Maybe an ~18-80? Does something like that exist? Reason I ask is I can't always get right up on a subject that's on stage or whatever, but I don't need a telephoto to get a tight shot either.
I know Nikkor makes DX lenses in 18-70 and 18-135 (D80 kit lens). Anyone have any experience with those?
Also Ken Rockwell raves about the Nikon DX VR 18-200 mm F3.5-5.6G Zoom. Seems like a good choice (though I'd have to save up for it since it's $1000), but some critisize his reviews.
If I am stuck more in the 18-55 range, what lens would be a good, not super-expensive, upgrade from the D50 kit lens ([SIZE=-1]Nikkor DX AF-S 18-55mm f/3.5-5.6G ED). The kit lens only does 3.5 at it's widest, which isn't TOO far from a 2.8, but obviously if I could open it up some that alone would help.[/SIZE]
As for more light, I can only reasonable have one - a camera mounted speedlight. I already have an SB-600 and diffuser so I'm pretty good in this respect (at least as good as is reasonable for this shooting situation).
