Looking for a SLR camera - any suggestions?

[Mr.Maduro]

I decided to upgrade from my Sony Cybershot digital camera to an SLR.

I purchased a digital photography book and intend to read it cover to cover and really get a basic handle on photography.
I'm looking for something that will be easy to learn all the features but also one that will allow me to do evertything I may want to do.

People have been saying the Nikon D80 or Cannon Xsi are good entry-level SLR cameras. I'm still a little partial to Sony.

What do you photography buffs reccomend?

I'd like to keep it below $1000, but could justify going over if it will really make a big difference.

Thanks in advance for any/all help.
