After being a point-n-shoot guy for ages I'm finally ready to take the dive into DSLR. I've been trying to research online but I'm getting bogged down in terminology, particularly when it comes to lenses. I have however learned that you are better off spending money on the lens rather than the body. So it's with this mind in that I'm posing the question to you experts -- if you had $500-$800 dollars to spend on a body and lens, what would you go for? I've been eying up the Canon T1i w/ lens kit, but I'm wondering if my money might be better spent on a XSi with a better lens. I would like the ability to shoot video with the camera, but it's not a requirement. The main thing I'm looking for is crisp, vibrant images and the ability to shoot quick action shots in succession. For instance, if someone was playing basketball I'd like to be able to hold down the shutter button and take 3-4 images per second but have them come out looking as nice as possible. Any advice would be greatly appreciated. Thanks!
