"This of course brings me to more thoughts and concerns... If we have an instructor teaching us incorrect technique perhaps we should take a closer look at our instructor, which we have not made any serious financial committment to as of yet. If you cannot trust the advise given to you from an instructor, what do you have??"

Unfortunately, you could be studying with a world champion, and still have a teacher who is teaching you wrong technique. It's just a matter of degree.

Probably the best thing to do is to look at the teacher's current students. Do they look like they are making progress against their goals? Is the balance of having fun vs. banging head against the wall in frustration the one you want?
