I have about $850 to spend and I don't know which of the three to buy. I've pretty much narrowed my list down to these three cameras, and I'm leaning towards the T1i the most (followed by the Nikon D60). Yet, the reviews for the XSi seem to be the best out of the three. The local camera store has the T1i for $850, the XSi for $750 and the D60 for $649, all of them come with lenses. Which would you say is the better buy? Thanks in advance.
