Thanks for the input, guys.
But, I think I'm going to go with my gut and get the Pentax K100D or K110D. It's cheaper, just in case I don't use it as much as I'd like. But I'm really hoping to get into photography, it's very interesting!
Neither the K100D or K110D are bad cameras, but if your able to get the K10D for 10 dollars more I can't see any reason why you wouldn't. The K10D is a beast of a camera.
If you were wondering, it's the camera I use. You can view my work from it in my signature.
