I suggest the Sony A200, or even better, the A350 if you have the extra cash.
My reasons will be,
1) built in antishake, making every lens you attach stabilized
2) very intuitive menu system. (although ANY system will be intuitive after using for a while)
3) i love the grip. it feels very adequate
4) (A350 only): the liveview is awesome, together with the tilting LCD.
apart from these, i think you can't go wrong with any of these cameras. they all take fantastic images and have more than enough accessories/lens than most people could possibly afford.
Snap snap away!
the 3 AF points are place in a way that they allow me to visualise the rules of third in a vertical way but of course the hortizonal way i just have to make do with my "gut" feeling.
after you spent a few years in practising, the so called "gut" feeling more or less will grow naturally so just have to spend some time practising whenever you're free until you get the right kind of feel you wanted.
sorry think i have OT a bit here.
To me any brand of DSLR is a good piece of equipment.
Image quality is almost about the same for all brands to me, but most importantly is the ergonomics of the camera that I take into most consideration. Find one that you are particularly comfortable with, and you'll find yourself loving your camera!
So long as you choose a particular brand, just stick to it all the way.
i would suggest trying it out to see which camera feels comfortable in your hands. no point getting a camera but it doesn't feel right. then u need to get a battery grip which may cost more.
just to share: i was contemplating 400D but it doesn't feel right in my hands. the D80 felt better. but due to budget constraints, i had to settle for a 2nd hand 30D from B&S section. very happy with it
