Would be a shame not to mention Naroditsky. Watch him play through lower rated players and give you great insight to both his and his opponents thought process.
I watch all of his videos but if you are starting, 'Building habits' is definitely much better, Aman will often keep making the simple moves he preaches even when more complex ones are available just to drill it into you. Naroditsky, while a great teacher and highly educational can't help himself from playing overly complicated lines that people at those levels wouldn't see. Hikaru is even worse in that respect (tho he doesn't attempt to be particularly educational in the first place anyway).
Other than that, I'd also recommend John Bartholomew who also explains his moves thoroughly in his series where he plays lower rated players.
