I will be needing something in that range as well, but will likely go Nikon, D7000.
Just used a friends 5D MKII for an afternoon, together with this super funky lens,
I liked it, the camera itself - it's nicer than then Nikon, really, design wise, it's rounder, it's lighter..
..but, having used Nikon the last year I really got used to them / got fond of them.
One main aspect is, really, I can 'hang' the camera in the buckled fingers of my hand,
and it doesn't slip off - Canons grip is smaller / thinner, so it slips immediately.
Oh I so wish they'd build cameras in different sizes...
