Only micro adjustments on 7D matters. I never need this function on my 60D, because I do tests when buying lens.
Don't listen if someone tells 60D is plastic. That's rediculous! there are no plastic SLRs - they all are metal inside.
60D is the best Canon choice for video. You can use Magic Lantern on it, but not on 7D.
Your lenses are too big and heave for crop, I''d advise to go for 5Dm2. so 60D or 5Dm2 - my Imho.
"your lenses are too big and heave for crop" what do you mean ?
Yes they are all metal Inside but not on the outside ... the plastic will take far more scratches and will look and feel old much faster than metal.
For example the plastic card-door on my 7D looks so much more just than any of its metal-bodyparts.
And when I compare my old 40D(metal) and 350D(plastic) the metal on the 40D doesnt really changed over the years but the 350D does and is now looking and feeling like it will fall apart every second. Also the gaps between the body parts get bigger over time and much more on plastic bodys.
