My sister is in the market for a new digital camera as she loves photography. She wants something easy to use (not complex) and that has a good reputation for quality and takes good photos. She is considering these models.... Nikon D90 Canon Rebel XSi (or Rebel Xti) Canon SX10 IS Nikon D40 Canon PowerShot G10 or G11 Any thoughts and/or recommendations? I have heard many good things on the Canon Rebel but I am not sure what model as I think there are 2 or 3 different Rebel models. Also, who has the best deals on new digital cameras (either store or online)?
