I got it and returned it, one of the guys at my flight school has it and he let me borrow it. As far as "quality" they are a little cheesy from a video and musical standpoint, but they have good info and you will learn from them. I also learned that my flight school has the whole collection on VHS in the library. Savin' some $$$$$!! Just have to go buy a VCR; I thought I would never own one again.
