Hello

I am new to the forum and know absolutely nothing about cameras of photography and was hoping some of you could help me or tell me the right place to post where maybe someone could. My girlfriend loves photography and one day dreams of starting her own little business. I want to buy her a camera for christmas and was looking at a cannon t3i. The lady at best buy told me that this is a good beginner camera but my only problem is i dont want her to have to buy another one next year. Is this a good one for her, could she make a little extra money with it as she learns more and gets better until she gets a better one? Which one do you suggest???
