Canon 55 250mm Is
I want a Canon XSi, but … Im getting a Canon XTi w. ..?

XSi kit lens (18-55 f/4-5.6mm IS), and 55-250mm IS lens f/4-5.6mm Canon and free … it's better or the same, because I want quality

None of these lenses are particularly wonderful. They work very well and most people will be perfectly happy with them, but if you want real quality going to have to spend a hell of a lot more money than that.
