I'm looking to get a t3i mostly for my wife. She currently has a E series Olympus, but would prefer a Canon mostly just so she can swap lenses/accessories with others she knows. She found a basic kit for $439 with a 18-55/3.5-6. I normally look used. Most of this equipment doesn't really wear out, and we are far from needing top of the line, but I would think if I can get brand new for $439, then I should be able to spend $439 on used and end up with better equipment.
Do my expectations carry over into the Camera world? Most of my experience is with music gear.
Also of interest, is Canon t3i a full description or are there version numbers with different specs I should be aware of?
