I found a great way to get a good camera. My old D80, which got god pictures, although I had to fight the metering, is fastly approaching the end of it's serviceability. After 95,000 shots, it's not quite up to the job. When I compare it to the D300, it's like the difference between a Porsche and a VW. The D300 consistently meters and its a joy to use. The D80 works, but it's always a chore. So I figured since it was about time to replace the D80, I went out on Amazon and looked for a used D200. The D200 new was not cheap ($1,699 when released in 2005). But now with more advanced cameras out there, you can find a used one for a fraction of the cost.
I set my budget for a backup camera at no more than $400. I found a D200 with just under 8k shutter activations for $180! And it came with 2 batteries and a couple of cards (I will be getting better ones as these are the slower cards, but still a nice throw in). There are no official numbers for the shutter life on these, but the going consensus for the D80 is 50-75k shutter activations. The D200 consensus is 150-200k shutter activations. So getting one with low shutter clicks at a low price can be a challenge, but there are some nice deals out there.
The D200 came yesterday and it is damn near new. Clean, low shutter count and well cared for. So if you are looking to upgrade and on a budget, watch Amazon for used, older ones that were well cared for and you can find some amazing deals.
Here is the D200 and the D80 side by side.
