Hello...welcome.
First of all, ask yourself these:
1) Are you ready for a DSLR?
2) Do you know what are the other stuff required (lenses, dry cabinet, filters for the lenses, etc)?
3) Have much do you know about photography?
4) What is your budget?
Please also note that owning a DSLR does not mean that your pictures will be amazing. If you are not ready for a DSLR or if your budget is tight, consider getting a prosumer (bridge) cam instead.
If you are ready to get a DSLR, I would suggest that you go to a shop to try out the different entry level cams from each brand (Nikon, Canon, Sony, Pentax, Olympus, Panasonic and Samsung) and see which suits you best. Popular brands does not necessary mean they are suitable for you, get something which suits you and you're comfortable with. Afterall, you are the one using it.
