Hi Richard

Most of the videos I've viewed are of good quality.

I'm not sure about the overall quality as there are so many videos available it would take quite some time to get a representative sample.

I would recommend a months GT subscription and then you can have a good look through all those videos that you might use. That way you'll get your own feel for them. If you like what you see renew if you don't jump ship!

I've got a feeling you'll renew :)
