After much more reading I am adjusting my question as follows if anyone would like to post.
I am trying to make a digital still camera decision and the more I read the more complicated it gets. Basically, I want to get the best camera I can and pay nothing for it.

Well you get the picture.
My primary interest is to be able to take the highest quality digital pictures I can just in case I want to blow them up. I also need to be able to take pictures that are of planes far enough away to require zoom and closeups that may require a wide angle lens to get everything in.
One thing that impacts on this is the fact that I currently have a Canon EOS650 film camera with three Canon EF lens (100-300 telphoto, 55mm std and a 28mm wide angle I think). From my research it would cost me about $600-$800 to buy just a Canon EOS digital body that will accept the lens I have. But it appears I would end up with a very high end setup compared to some of my other considerations.
Things like how much zoom and image stabilzation are confusing me. but I am looking at two cameras other than going to EOS route. The Kodak DX7590 and the Panasonic Lumix DMC-FZ15.
I really like the Photo Dock capability to just stick the camera on a box and make a print. I have not been able to find out if the Lumix has the same accessory. On the other hand I think that the image stabilization on the Panasonic would be nice for all my at the RC field, and out on the lake fishing and boating pics.
Anyway, I would like anyones opinion on the three options, or maybe it’s just two – the Canon EOS route or pick between the Kodak or Panasonic.
Thanks, Steve
