Keep in mind that for DSLRs, lens >>>>>> body in terms of importance.
If you can purchase a cheaper DSLR and get better lenses you'll be happier with the results.
That said, $600 is really cheap for a T4i.
I got in on the BHP $649 deal for the T3i with 2 additional lens, memory card and bag... Should I ditch that one to take this???
