If weight/size is a concern, I would STRONGLY recommend the new Canon Rebel xSI (aka 450D, should be coming out soon, but the current/old models can be found cheap now). The functionality of the Rebel body is very similar, and in some ways better than the Canon 40D.

Oftentimes more important than the body is the lens, but the kit (included) lens for the Rebel (18-55mm with image stabilization) should be satisfactory for just starting out and learning the basics.

Nikon fans will of course steer you towards the Nikon equivalent of the Rebel. And to be fair, the Nikon equivalent would be fine as well.

My recommendation, if you're just starting, is to get the cheaper Canon Rebel XTi (just the body http://www.amazon.com/gp/product/B00...SIN=B000I1ZWRW) and get an all-around lens like the Tamron 28-300 w/ Image Stabilization http://www.amazon.com/Tamron-28-300m.../dp/B000V6ON8I

Allin only around $1100. If you hunt around you could probably knock off around $100-200 probably through different retailers, merchants, or ebay.

Generally the two most important things in photography are (1) the lens and (2) the photographer. That said, I love my Nikon D40, don't see the point of the D60, and wish the D80 were updated. For your budget you can get a pretty decent body, lens and flash. You will want a flash. My advise it to go to a good camera store and play with several. You need to hold the camera, shoot with it. Play with the settings and how to change them. You are going to drop some out of contention because you can't stand some small thing about them.

Remember, this is a long term relationship, and an intimate one at that. Take your time.

Then go have fun.
