Guys, you're doing one of two things well.
1- listening - you're doing
2- feeling - you're not !!!

Go to a shop and feel the difference between all the cameras yourself. I couldn't manage a 350D even if I loved its technical features and was recommended by 100% of my friends... it's too small for my hands. Bit late to find out after shelling money on the internet

As for information on lenses, VR, etc... check out my posts starting here: https://passionford.com/forum/pictures-video-and-photoshop-forum/176542-photography-101-lesson-one-cameras-and-lenses.html

you should find some useful info there (hopefully ).
