I bought the 60D recently since the body only price was around $888, which is a real steal for me. The 60D has at least 2 stops of ISO improvement over my Canon Rebel XSi (450D). I find that the 60D has as much noise at ISO 3200 as the XSi at ISO 800, which is INSANE. In my observation, the battery life is around 1,400 shots for me, which is very impressive.
The brighter pentaprism, video, better grip, superior build quality, top LCD, flip screen, great controls, and amazing autofocus makes it one heck of a great camera.
