Haha yeah, it is funny that they look like a UFO isn't it?
I think the best place to buy is Handpan Guru. They have reasonable prices and they have free worldwide delivery.
I was putting off getting a hang drum for a really long time because of their high price. I finally decided to invest in one and I AM SO GLAD I DID. Last week I got the 7 note handpan from https://handpanguru.com arrived and it sounds amazing.
Good luck with your purchase!
