Replying to Camera Help

K guys, I know there are hundreds of threads out there asking the same questions, and I read quite a few of them and then decided it'd be easier/i'd get the best response if I just created my own thread.

Alright, so I'm looking for a camera. I would use it mainly to take pictures of landscapes and buildings and things like that (not many portraits or anything, and not really for filming). I My budget I'd say is somewhere in the 500-800 range. I have photoshop, but I've never really used it before. I have used editing software in the past but only for videos (power director and vegas pro) and I was fairly comfortable using those so I think I'd be able to figure it out pretty quickly by watching tutorial vids and all that.

I know 500-800 bucks in this market isn't a whole lot, but for now I'm not really looking for anything too too fancy; just something that takes good pictures and that I can build from in the future. I was looking at a few DSLR's but there are so many different models and everything that I'm having a hard time deciding which one to pick. I've only ever used low end point-and-shoots til now so I'm pretty new to all this. I wanted to see if you more experienced photographers out there had any advice for me?

Thanks guys
