Tuning?

I really want to buy a hang drum, i can save up the £500 needed within a few months, but im not sure what tuning/scale i should go for?

Im used to playing guitars & keyboards & just looking for an all round nice sound, what would be a good tuning to go for?

Im definately going to get one i just want to have all the info ill need before contacting them in swizerland, if anyone can suggest how i can help the process smoothly id really appreciate it

Thanks
