The best camera is usually somewhat subjective, even in different price ranges. There are many manufacturers out there with cameras in different levels that all compete with each other, much like any other product in this world.
That being said, there are 2 main manufacturers that the majority of DSLR users go for, Canon and Nikon. I would recommend going with one of those 2 for the simple fact that there's a huge used market that will make good lenses more affordable. I don't know if either offer a touch screen or how useful that would even be with normal usage.
As stated in this thread, good photos are almost entirely made by the person taking them. I would get on youtube and start searching for videos about beginner photography, etc... Keep in mind there's a fair learning curve before you start getting anything overly nice.
I personally use a nikon d7100. You could start with a D3300 or D5300 if you wanted to save some cash. You could even find a nice used D90 or D7100 for a great price. I can't really recommend any Canon options, but there is a lot of info on google about any brand options. In that price range your best bet really is used, especially if you want lenses with that price. My cheapest lens was $200, my most expensive was $2400.
