I have been saving to buy a third body, I already have a 40D and a 20D and will probably sell the 20D when I get another body. So my heart was set on a 1D series body with the MKIIN being the one I can more easily afford. But is it a good upgrade from my 40D or should save a bit more and get a 5D MK1 (the 5d MK2 is out of my price range) or a 7D?
My thoughts so far:
1D MKIIN
For:
Pro body therefore more durable and better weather sealing
Excellent reviews on the internet
Dual memory card slots
Against:
Older technology
Usually well used
7D
For:
Latest technolgy
HD Video
Almost as fast FPS as the 1D MKIIN
New AF system
Against:
Relatively untried
Lots of people complaining about image quality
5D
For:
Full frame
Good reports on image quality
Against:
No weather sealing
Slow FPS
So am I missing anything?
Has anyone used both the 7D and 1D MKIIN? If so what are your thoughts? Any advice is appreciated.

So I'll ask this one question, is the AF on the MKIII as bad as some people say? I hear people complain about the 40D but I've never had any problems with mine
