Is the Canon EOS Rebel XSi and/or the Tli and good camera?

I want to buy my first dslr camera. I have been looking at the Nikon d5000 and d3100 for months now. Last night I stumbled apon the Canon EOS Rebel XSi and the Canon Rebel Tli. I liked that they were a little cheaper than the Nikon. Would one of those be good cameras for me to start with?

I own two Canon dslr cameras, the Rebel XS and the t1i - they're both excellent. I've the XS for well over a year and am very pleased with the technical quality. The XSi is the next step up from the
XS and is just a good as its cousin.

The t1i also does video, as you probably know. The video is clean, crisp and very nice. The stills
are sharp and crisp. I'm really enjoying both cameras.
