I'm looking to hopefully get an SLR before my birthday which is June 2nd. I've narrowed it down to the Canon T2i or the T3i. I don't know a thing about an SLR camera but was told both of these are very good. If you had a choice which one would buy and why? Why wouldn't you buy the other one? What's the big difference between the 2 if there is any? All I know I want one within the price range of these 2 and that are very good for video and low light.
