Canon's budget digital Rebels have been one step ahead of their inexpensive DSLR competition for years. The Rebel's latest incarnation, the Canon EOS Rebel T4i, builds on that tradition with innovations you won't find on even the most expensive DSLRs. It brings touchscreen controls and new beginner-friendly video features to an already great camera. But it'll cost you.
For the money, last year's T3i is a fabulous camera. It's a popular shooter, but compared to the T2i that came out in 2010, it didn't bring a whole lot of new features to the table. Sure, it has a swivel screen borrowed from the more expensive 60D, which makes shooting video easier. But other than that there isn't any other reason to splurge on the T3i when you can find T2is for cheap.
