Hall of Famer
The Nikon D5100 is currently in stock and shipping from Amazon. This is the most compact DSLR to house the remarkable sensor from the Pentax K-5 and Nikon D7000. I previously owned a Nikon D5000, a fairly small DSLR itself, and the newer model is even more compact. At $899 with lens, it looks to be a strong buy.
