Hi, Ive been researching some digital cameras for the past couple of weeks and decided that id like to get a 7 or 8 megapixel Canon Elph. Problem is, there are just too many options and im not sure what I need. Im up in the air with the SD750, SD850/870 and SD1000/SD1100. Couple of questions: 1) How important is an optical viewfinder? Will I really not be able to see the LCD screen during the day/in the sund? 2) Lens-do I need one of the wide foucs ones? 3) Which of the above has the fastes flash speed and will I notice a difference in these speeds? 4) Lastly, how important is Image Stabilization Thanks much for the help!
