You meant to title your post: "How to find an excellent teacher"!
Do you occasionally go to a language teacher for lessons to check to see if your ability to speak is going in the wrong direction? I know I certainly do because I don't want my E's to go in the wrong direction and sound like I's.

Technique is the same way.
Excellent teachers are usually the ones with excellent students and I'm not referring to how well they play. I'm referring to the students ability to listen, understand, and follow the teachers instructions. That means the students practice their assignments on a regular basis, shows up on time for lessons, etc. These behaviors result in excellent playing.
So if you are only looking for a decent teacher...
