This is a great website using which you can easily register new gamertags of your choice. We not only offer an availability checker for gamertags but we have also designed our own generator. We have received feedback from hundreds of users that they have got a great name on Xbox due to our tool.
This started as a hobby but has turned into so much more, We feel proud to say that a few of the top gamers in the world are using names generated by our tool.
We hope it helps you too!
