Well Gary, I think the answer is YES, the only remaining question is when
The only thing that's really holding me back is that the EOS 3 is, I believe, a superior camera, particularly with regard to autofocus - otherwise I might be very tempted to trade one of 'em in aginst a D30. I'm thinking of hiring a D30 for a week or so to use in the field alongside my EOS 3 kit and see how it all works out in practice.
I'm starting to think along the lines "well, if I buy an D30, I won't need to buy a 600mm lens, as it will magically transform my 100-400, so I'll actually be SAVING money" this is a very bad sign. The next stage to ruination is when I start trying to explain this logic to my wife!
