They both really seem to like the 18-70mm one. I think I am going to get that one. It is a nice compromise between price and quality I think.
If you do, I don't think you'll be disappointed. However, like others have said, the 18-70 does have its limitations, so don't expect miracles!
For example, if you are upgrading from a consumer P&S superzoom, you may severely miss the range. It also isn't the best in low light. But then with the D50 you can shoot at ISO800-1600 to pick your shutter speed up in low light, and get results that would be next to impossible (noise-wise) with even the best P&Ss. And then there is also the satisfaction of the camera actually taking the shot when you press the shutter - this kept bringing a smile to my face for months!
I ended up pairing my 18-70 with a fast wide-angle from Sigma for indoor available light shots (Nikon doesn't have anything at the moment).
If low-light portraits (need a short telephoto lens) end up being your cup of tea, you can't go wrong with either the Nikon 50/1.8 for 100 bucks, or its slightly faster cousin, the 50/1.4 for $250.
The best thing about a "kit" lens like the 18-70 is that it allows you to figure out your preferred shooting style without shelling out a huge amount of money in the beginning.
You may find you just want to take snapshots, in which case, this is the only ever lens you'll need. But if you get into it, you will start to notice where it is that you are being limited by your gear.
This could push you towards low light prime lenses, wide angle zooms, or fast telephoto lenses for sports/birding. But even then, I bet for everyday use, the 18-70 will stay on your camera the most.
Good luck, and enjoy!
