I agree. A good tea shop will have many, many teas and will sit down with you and let you try some until you find what you like.

In the end, it's all what you like. I have had very very expensive teas which I thought tasted terrible, and I have had moderate priced teas that have been some of my favorites. Many teas (pu erh comes to mind) are really in the eye of the beholder and can be an acquired taste.
