Your views on Sportech Cranker Tank Bag

[dealrocker]

I was looking for a cranker tank bag for my brother and found 'Sportech Cranker Tank Bag' at BikeBandit. It features an integrated amplifier, speakers and MP3 capability so you can take your music with you and still have room for your riding essentials. Want to know your advice and suggestions before any purchase. Does anyone have any experience with this?

Thanks...
