I'm glad you've experienced Groove 3 products and agree their products are top notch.

For me one consideration is how the video series is organized. While the series has almost two hours of content individual videos are fairly short at 2 to 8 minutes in length. Since each video has a description the video series is very useful as a resource. You can watch the series in one setting to gain an appreciation for Band-in-a-Box as a whole then zero in on specific video subjects as the need arises. I watch specific videos as a refresher when I haven't recently performed a task.
