I have this Dvd box set and it is really good, this is an amazing price I have never seen it so low. I thought that I got a great deal when I paid £17.99 for it! They are always on eBay for much more!
Just to add - if you find the classes on these DVD's a bit of a struggle to begin with Maya has a class that is less demanding 'Detox and Destress'. This is the DVD that I began Kundalini Yoga with and still use it regularly. It retails on amazon.co.uk for approx £6.49 and includes a bonus CD of Maya's mantra music which is beautiful. Kundalini Yoga is different to Hatha Yoga in that you are seated more and there is more focus on the breath and movement is continous throughout a lot of the class. I have practiced Hatha Yoga and loved it but when I discovered Kundalini Yoga it became my daily practice and the benefits are fantastic for me.
Price back up to £30.99 on amazon.co.uk now but Play.com have it at £17.99 which is what I got it for - haven't seen it for less than that before.
