I decided to make a change regarding teachers. After having studied for quite a while with teachers in the 18-22usd an hour range I decided to experiment with finding a cheaper main teacher. Six weeks ago I found a teacher charging 10usd/hr to go through the Hsk 4 book with. She has a nice standard accent(哈尔滨）and is engaging. I also found 2 teachers that charge 5usd/hr. to do discussion/speaking only exercises with topics I provide them.
The last "pricey" teacher I had was more skilled and experienced, but probably only 20 percent "better". Now I can have 4 lessons a week for less than I was paying for 2 lessons. In the end I think the loss in quality, is outweighed by more time spent listening and speaking.
