Depends entirely on the range you want, and how much you want to spend.
The zoom lenses I posted above are high quality L glass, and are my personal choices. Not everybody wants to invest that much in a camera/lens system.
The problem with picking an all around zoom for a crop body camera is that 24- and 28- really aren't very wide. There are a handful of ultra-wides available (like 10-20mm), but they're pricey for their limited range. 17-xx and 18-xx lenses are more general purpose, but a lot of these have some drawbacks as well. In that group, I lean towards the 17-40. The sigma 17-70 is another solid lens in this range. They call it a macro because it can focus closer than most lenses, but it's not a true macro. Still, it has a lot of versatility in one lens. If you don't mind a 3rd party lens, that could be a solid choice.
If you're looking to go cheaper, the 18-55 kit lens is probably the best place to start. It has a lot of shortcomings, but the price (~$50 used) can't be beat for a starter. Another interesting find is the old Canon 24-85, which is mediocre on a full frame camera due to poor edge performance, but gives surprising results on a 1.6x crop body by using the sweet spot of the lens.
For longer lenses, there are a lot of options in the 70-200 and 70-300 ish range. Largely, you'll get what you pay for here. Some are fantastically sharp, others are soft. It really depends on what results you want. The 70-200 f4L is my favorite lens out of everything that's in my bag. Color, sharpness, etc. from this lens is simply phenomenal.
