are you talking about the 5D or the 5DmarkII

T1I and the T2I are all good quality I just wanted more frames per second
If you had $1,500 in hand and your goal was to get the best camera + IQ possible, which of these 3 would be ideal? I am sure I will step it up to some $1k+ lenses in the future, but I need a camera to get started.
