The new Canon XTi has a 10.1 megapixel sensor, a 2.5 inch LCD screen, and a new dust cleaning system. It borrows a lot of other recent innovations from its brother EOS cameras and comes in at $100 less than its predecessor. DCResource has just posted their review of this DSLR and reports-

"While most owners of the Rebel XT probably won’t run out to upgrade, the Canon Digital Rebel XTi (EOS-400D) is a most impressive entry-level digital SLR. It offers great photo quality and performance, plenty of features (most notably, a dust reduction system), a large LCD, and plenty of accessories. The main downside is its design: it’s pretty small, not terribly easy to hold, and more "plasticky" than other D-SLRs. Despite that, the Rebel XTi earns my recommendation.

Some other digital SLRs worth looking at include the Canon EOS-30D, Nikon D50 and D80, Olympus EVOLT E-330 and E-500, Pentax K10D and K100D, and the Sony Alpha DSLR-A100."
