If that is the case, never ever again spent a thought on the D3 and avoid talk, touch and think about it as the plaque.An excellent suggestion by yamo, but I suggest that you... DON'T DO IT!
Unless you want a hole in your bank account and the wife to really be mad at you. Use the D3 for a while and you WILL have to have one sooner rather than later.
Thanks for the warning. Because my D300 feels very fast and snappy for me (former user of Canon 40D). Autofocus seems very fast and genius. I don't want to be disappointed and/or killed by my wife, thus I will make sure I will carefully make sure never to touch D3...let alone try it
With that in mind, I've seen D3 as low as $2500 on a local craigslist (which of course could a fraud)....but generally over $3000
I used my D300 for more than one year and was absolutely happy about it.
I touched a D3 once in a shop, touched it another time later and could not get rid of the itching since then.
I bought a new one earlier this year and whenever I have to use the D300 (when it just is more appropriate - longer reach, good light, CLS flash, lightweight, …), it feels slow and point and shootish wink.
Get your way around the D3, it is more healthy really.
