FRom that list I'd take the cannon, they are and have been in the lead of dslr's.
But you might also want to look at the new Sony A100 dslr, it's brand new, i just picked one up as a lesser expensive backup while my cannon gets sent off for service. (I've been using my cannon d30 since 2002 and it finally seems in need of something)
Anyways I am impressed with this Sony! It has a couple neat features that no other SLR has.
Built in Image Stabilization on the chip so no need for super expensive lenses to have image stabilization.
second is DRO, i tested this and it works super. No more dark areas in the shadows in bright sunlight. It really works well.
10.2 effective Megapixel CCD, produces images at 3872 x 2592
Super SteadyShot CCD-shift image stabilization system
Sony/Minolta Alpha mount, supports most KM lenses and all the new Sony ones; 1.5x focal length conversion ratio
Dynamic Range Optimizer is a hardware solution for improving D.R.
Two dust reduction systems: special coating on sensor repels dust, and CCD "shakes" the rest off when camera is turned on/off
2.5" LCD display with 230,000 pixels
Full manual controls (and then some), as you'd expect; ISO goes up to 1600
RAW, RAW + JPEG support
Unlimited JPEG continuous shooting at 3 fps; RAW cuts off after 6 shots (though I did better)
Hot shoe for external flash (though it's proprietary)
CompactFlash Type II slot; Memory Stick Duo adapter included
USB 2.0 High Speed support
Uses new NP-FM55H lithium-ion battery; 750 shots per charge
Ships in July for $899 body only or $999 with a Sony 18 - 70 mm lens
