The Nikon D80 was my first dslr, I bought it when it first came out for 999 shipped with kit lens. I really had no clue what kind of photos I would be taking, but I thought it would be pretty close to everything. After a couple months, I noticed that I enjoyed mostly motocross, and nature of any sort. The fps of the D80 was a little disappointing, but not a deal breaker. I also liked shooting as the sun was going down, or down but still light. The high iso performance was a little disappointing, but not a deal breaker. So after a couple months of shooting, I had passed 5k actuations. Just for kicks, I looked up how many clicks you can expect from the D80, which is 50k. I thought...wow, I
could be 1/10 of the way through my cameras shutter life. I
might have to fork out a few hundred bucks for repair later in the year. I don't know how money flows in your house, but here, spending 1k on a camera was torturous. So, that paranoia combined with poor high iso performance, and low fps, were enough to convince me to switch. I sold the D80 for 900.
I picked up a new sealed in box 30D with kit lens for 1040 shipped on
ebay. I bought a bigma to satisfy my motocross needs, a 50mm 1.8 for people/pets, and I am saving for a 10-22 to satisfy my wide angle needs. The 30D has a shutter life expectancy of 100k, which gives me a little peace of mind. I don't know the size of your hands, but the 30D feel soooo much better in my hands than the D80. I definitely would not let that effect my decision though, as I can get used to ergonomics, but I can't get used to poor performance.
Enough Nikon bashing, I have some good to say! Something I really like about the Nikon, any old afs lens fits the D80 body. I love old Nikon glass, they can be had for a song, and I don't mind using them manually for stills. The D80 doesn't meter with them, though it's not a big deal, you can just take a couple of test shots. I also noticed that the D80 captures significantly more information in the shadows than my 30D. I can pull way more detail from dark areas in pics taken with my old D80. Also, you
could buy(or borrow

Noise Ninja, that will clean up a stop or two of noise. You could probably buy the D80 for a couple hundred less than the 30D, that would be enough to get another lens. Lenses are what give you the flexibility to be creative. Odds are, you will love either camera. It just happened that the 30D fit my needs better.
