Tamron 171A Zoom lens - 28 mm - 200 mm - F/3.8-5.6:
I paid less than $100 with shipping for mine and even though it is not a Nikkor I find that I get a lot of use out of it for chasing my 3 year old, hiking, rock climbing, a few trips to Disney World, and lots of general landscape stuff.
It works on all my Nikon bodies FA to D70, (except the Nikonos V), it's really light, and at f/3.8 I find it fast enough for me. The only complaint I have about it is that sometimes it will seek focus, other than that it has served me quite well. FYI I only bought this lens because I needed a lens to abuse on a rough hiking trip I was planing, I figured for $100 I would take the risk, it was worth it.
Prices on these dropped like a stone when Nikon introduced the Nikkor 18-200mm VR, and if your pocket can take the $750 price tag this is the better choice, but still the Tamron is a great little underrated lens.
Good luck and let us know what you decide.
