So I'm finally going to buy a DSLR and I've been a fan of Canon for a while (I currently have one in their Powershot SD series). I realize these cameras differ in their specifications and prices but I'm willing to buy either of them...I just don't know how to choose. Do I get the Xsi which is now down to $550 on Amazon or do I get the T1i that is $750? I feel that one of the big differences that may cause me to lean towards the T1i is the video mode (which the Xsi lacks). I know I might want to shoot some video, but should I just leave that video shooting to my little Canon point and shoot? So do I save $200 and go with the Xsi or splurge for the $750 T1i? With the Xsi I may use the money I save and get a telephoto lens (which may add an additional $50 and put my budget up to $800)--Is this worth it as well? Any advice or opinions would be great! Thanks!!
