Skillful Buddhist Meditation Teachers
As far as my curiosity managed to spread to far, I think Ajaan Fuang is a great example. Not much is known about him except for a few transcribed talks and some quotes here and there, and some stories told by his students of their experiences with him.

One thing I remember about him, as far as being different goes, was that one time some Thai Monk Magazine (or something along those lines) went after him, trying to get an interview. When he heard about this, he avoided them at all cost. Finally they managed to pin him down somewhere, and asked him, "Could you give us a dhamma talk?" His response was, "Yes. Today's dhamma talk is one word: 'buddho.' If you can't keep this in mind, there really isn't any point in my telling you anything else."

Another great quote is,


  If I have to explain everything, you'll get used to having things handed to you on a platter. And then what will you do when problems come up in your meditation and you don't have any experience in figuring things out on your own?


I highly recommend the book Awareness Itself available for free at DhammaTalks.org.
