Right now, we use a combination of camera/lens.
For Digital, we have a simple point and shoot, the Nikon Coolpix-4300. It works nicely. We've had it about a year, and really like it.
For film, I use a Nikon F100 primariily with an 80-200/2.8 and the 24-120/3.5-5.6. I really like the 24-120; it covers a great range. It is amazing the difference of the 24mm bottom end compared to a 28mm bottom end. We also have an older N70. I cut my teeth on a Pentax K1000 in 8th grade, back years and years ago, but sold it recently.
So, what would I like in a digital??? I like the Nikon 4300 for a point and shoot. I would like to upgrade one of the film camera's to a Nikon D100. A D1/D2 would be sweet, but $$$. Above that, I can dream of one of the Kodak/Nikon 12+mp pro cameras...
I would stay with Nikon. We have lenses and stuff already. For glass, they are hard to beat. I wish Nikon would catch up with Canon with more image stabilizer and AFS/USM style lens offerings. Nikon has great glass, but is lagging on the other gizmo's.
You mention a Rebel in another post/followup. If you have lenses for it, maybe the Canon D10/D60 series would be a good option.
Lastly, depends on what you want to do. For point and shoot, digital is great. For a bunch of 3x5's, it's just as good as film. How many do you blow up beyond 5x7? That's when you start noticing differences.
We shoot mainly slides, in 64 or 100asa, off tripods. But, we blow stuff up too. We have some great whale shots from Alaska for example. 11x17 off Kodak and Fuji pro films came out
great.
A Canon D10 or Nikon D100, with a lens like the Nikon 24-120 would make an awesome combo.
