I vote that you get Nikon D3x with the Holy Trinity lenses too!
If you prefer Canon then 1Ds MkIII with L lenses..
Can't decide, then just buy both.
Don't worry if you don't know how to use or what ever just buy no regret, comfirm.
In Singapore you look fierce can a ready, you bring the body with some big lenses out and take pictures. Anyhow pose a bit and take a photo, people see a ready also scare. If the place crowded with photographer taking some subject, you just walk straight in and take photo also. They comfirm move a side 1 unless have some big gun also, see your setup they also scared! But if you want more fierce ah, you sling another 1Ds MkIII/D3x across your body. Comfirm no fight. ***
***But don't show people the picture you take, if you show don't tell them the setup.
Sorry for the crap above as I am too bored in office, just get canon or nikon body. For nikon do take note that d40x,d40 and d60 do not have built in motors. As a nikon user I think D90 will be a good start as it has 1 of the latest technology and it has a built in motor.
