I have been on the same path as you. Film -- P&S -- DSLR (DX) and now D700.
If you have the cash, get the D700 and don't look back. There is a joy of ownership with the D700 that will never be verbalized in any review, and which transcends technical pixel-comparisons.
If you take a lot of pictures of birds or distant small objects you might want a DX format. (Personally, while I respect exceptional wildlife work very much, I don't enjoy it myself.)
However, if you are wanting a camera that behaves like your old film bodies, skip DX and go right to a D700.
Then you can get a 50 MM 1.4 or 1.8 and a few other judicious lens buys and you are back where you were with film. For me DX just never felt right. It was nice having a bit more zoom, but....
Be advised -- there are many ways of looking at this and only one view that is right for you. I had to sell off three pieces of gear I loved to make this happen, and now there four people happy - the DX gear buyers and me. If they are as happy as I am (one buyer used the word "thrilled", the world is now a much beter place! And nobody has made a "wrong" decision.
The good news for you is that there are D300s coming up for sale that have been used no more than 8 months at a steep discount from new. The smart money is on a used D300 or a new D700 I believe.
