If you do decide to upgrade i may be interested in your d40 for my stepdaughter. For the right price
Its a 40D not D40, as in Canon not Nikon
Just sold my older one that had done close on 80K clicks, this one is the new spare and not even reached the 1K mark yet.
Trying to decide whether the 60D provides sufficient cause to spend out the extra on,big downer is the considerably less custom settings, only one against the current three and the change from CF to SD cards.
Might have to see how much a 7D would set me back, know the 60D would be made of strong plastic, but used to the metal shell and the extra durability
Will let you know should I decide to sell, would be looking for around the 380-400 quid mark given the condition.
