FWIW since this post was more than a week ago...
I just moved up to the D70 from a Sony F707 digicam.
I can't say enough good things about this camera for boarding shots. The kit lens is nice but not that long for getting tight shots of boarders at 75'-- I picked up a Sigma APO 70-300mm Super Macro II zoom lens for it and it was just what I was looking for. Better than other lenses in the price range (bought and returned a Tamron zoom before getting the Sigma).
- zero shutter lag. It's a DSLR. I hit the shutter release and get the pic I want. I guess if you're considering a 10D or other DSLR this isn't an issue
- great continuous shooting for a prosumer DSLR - about 3fps shooting
- great RAW mode shooting. NEF images are around 5MB and are great for post processing using Nikon Capture or Photoshop CS.
- low noise up to ISO 1600
- great kit lens for all around use-- much sharper and faster than the 300D's kit lens, not sure what 10D's are bundled with or if a kit is even being considered for you
- really fast overall-- the spooling of pics to the card are done off a fast buffer so the camera is really responsive even with slower CF storage cards. the UI is fast, and changing settings (for me) has become second nature. I hate waiting for my camera.
Having used a 10D and a 300D I think I made the right choice with the D70. Of course, with any of these, your photos are still only as good as your lens(es). So now I'm a "Nikon guy" and invested in Nikon compatible lenses. Something to consider.
