Go up to a 1D and you could drive nails with that body.
A 1D is a fair bit more expensive than the 7D or D7000.
One of the major reasons I bought a D7000 over a 7D was it's construction. ( This is of course apart from that fact that I already owned Nikon mount lenses.)
I've had a electronic problem with it though, but that happened once and many months have passed since then.
I like how this turned into a discussion between us about Nikon vs. Canon.
It's not even a discussion really, just random camera chatter.
And you should join the Photographer club as our first Canon owner.
