Can you help me choose the right Canon rebel camera model?

I am on the Canon website and there are 3 different types of rebels:
-EOS Rebel T1i
-EOS Rebel XSi
-EOS Rebel XS

I have no idea which one to get. I have never owned a professional camera before, so I won’t understand any fancy lingo having to do with megapixels and lenses. I do need to know, the ranking from highest to lowest quality in those models above and the approx prices. What you would suggest for someone who is new but also wants a good quality camera? (out of those 3 models)
