Anyone using a Canon Rebel XSi?

[Reef Pets]

I have considered upgrading my camera. I now have a Canon Rebel Xti but I really like the live view feature of the Rebel XSi.
I am curious to know if anyone is using an XSi. I mainly take Macros photos and was wondering if the live view screen is clear enough to see details of a macro photo to the point if I would be able to tell if I am in focus.
Any other information would be great.
