Buying a new DSLR.Need advice.

I work Asset Protection at Best Buy and my co workers that are into photography have all purchased the Nikon D5100. I also see it purchased by customers more often than the Rebel/T2i. But as a previous poster said, Canon and Nikon make great cameras.

The photos I've seen taken with the Nikon D5100 all look fantastic. I wish I could give more help with technical answers but not my department.
