Also, my
PowerShot SX130 IS has a 5.0mm to 60mm zoom lens, so what’s the difference between that an external with the same numbers?
You will not find any kind of a high quality lens with the sort of superzoom that you find on some P&S cameras. The larger the zoom ratio, the more compromises have to be made in image quality. For the best quality zooms, rule of thumb limits zoom to 3x-4x, meaning that the telephoto end is 4 times the wide end or less. The icon of Canon's lineup is the 70-200, and the mid-price range version is the EF 70-200 f4 L IS. It has a zoom ratio of 2.9x. The EF-S 17-55 f2.8 IS has a zoom ratio of 3.2x. These are 2 of Canon's highest rated zoom lenses for IQ, and they are right around 3x zooms. You need both to have the reach from wide angle to moderate telephoto. Together they would cost you about $2400 new. Granted that there are cheaper options, but they come at a cost of either image quality or speed, or both.
I'm not trying to scare you, just make sure that you are informed. When you buy the Rebel kit, it will probably come with the 18-55 IS lens, This is a good lens, especially considering that it sells alone for about $100. It has good image quality, especially when stopped down to f8 or f16. It isn't a fast lens, meaning that it's largest aperture is only around f4 if I remember right, and it doesn't have Canon's best autofocus system, but it's still a good little lens and great to start with. A reasonable addition to a starter kit is the EF-S 55-250 zoom, for about $300. It extends your range well into the telephoto end, and again it's a good lens with decent image quality for the price.
A great many users are quite satisfied with the kit lenses and never get into the crazy spending that us junkies do. There is no telling which category you fall into until you start down the road. I suggest that you buy the T2i or T3i kit with the 18-55 IS lens (and the 55-250 if your budget allows) and see how that suits you, then explore from there.
