I want to buy a Canon XSi

I have been looking at D-SLRs for a few months now and have pretty much made up my mind that I want a Canon Rebel XSi. I'm somewhat of a beginner to photography and I understand that. I have experience using a 35 mm film Canon SLR which was about the same as the Rebel XS.I know the basics of photography, but before I buy this camera, I want to know if there is anything I should look for before I pull the trigger and buy it. I will more than likely be buying the kit with the 18-55 mm lens. I would prefer something with more zoom capability, but for the price it's offered at, it will do fine for me.
