Yes, will be getting one for the business. We needed a back up camera anyway, and for the price it's a great deal. We will need some additional lenses but otherwise that should be it.
If I was buying one now it would probably be the 20D but could equally well be the D70.
I'm super happy with my 10D so in a few years when the next major advance is made I'll think about an upgrade.
Alternatively, if I win the lottery this weekend I'll buy the 1DS on Monday.
I don't need it yet. I can do everything I need with my rebel. I don't shoot action that much, and with relatively still subjects I don't need the super fast autofocus.
