I'm looking to upgrade to a DSLR and pick up rather quickly on how to use equipment. I have 5 small children who are active in school functions and sports. I need a camera that can take good action shots in low light. I have researched DSLR's online and am more confused than when I started! I have it narrowed down to Nikon D5000, D90, Canon T1i and 50D. I would SINCERELY appreciate any advice anyone can offer me. I have gone to Best Buy and played with each of these cameras and am comfortable with any of them. I just want what's going to give me the best pics. And of course, the lower the price, the better. But I'll tackle that issue later! Thank you so much in advance!!!
