The 24-70 f2.8 and the 24-105 f4 are both great walk around lenses for your camera and these lenses will also work on full frame cameras if you later choose to upgrade. Another great choice is the Canon EF-S 17-55mm f/2.8 IS USM. You may find on your T2i that 24mm is not quite wide enough and therefore the 17-55 may be a better fit. All three of these lenses have superior image quality to your kit lense.
