Ok. After many days of search my choices narrowed to 2 DSLRs. First one is made by Olympus, and second one is by Nikon. As far as reviews both cameras has cons and pros ( well of course). Though, many people are really inclined towards Nikon. So I am quite biased right now. 
In addition, I have never actually owned DSLRs, so anyone has suggestions that will be very helpful. Although I am a noob in a photography, at this point I am eager to learn more (even found websites and guidelines). 
So why DSLR? Well first of all I am in Badlands. A very rugged land with its beauties and wild life. A perfect place to shoot a dramatic nature scene (I guess not dramatic as ocean or sea), and I will be able to practice and understand more about camera's features and specs. Secondly, I really like taking pictures. It is a way to stop the time in a small digital frame. Thus, if you have some recommendations, I am always glad to hear about.
