I'm not sure if anyone else has covered the UK version of the Alien head yet but anyone who feared it might be inferior to the Japanese edition can sleep soundly tonight. The Alien head is of excellent quality. It is surprisingly weighty though a little smaller than I was expecting. This is to its advantage though as instead of a big hollow plastic piece of crap, it feels like its worth a lot and is noticably thick and solid. Inside there are 9 slots for the discs (obviously) though actually getting them out when you want them could be a bit of a chore as you have to remove the top of the head which requires it to be slid back and lifted off. Overall, I'm extremely happy with the head and it is easily worth the £64.99 I paid for it. Also, though the head itself isn't numbered (I haven't seen a number anyway), the box containing the head says "4085 of 9124" so I'm assuming that is how many are being made for HMV.
