Hoola Hoop workout?

I was thinking, since my bday is coming up, what I would like for my birthday. I was thinking of getting a weighted hoola hoop. But they tend to be a little pricey. I can't hoola hoop with a regular hoop, but I heard it was easier with a weighted one. I used to be able to, when I was skinny...but for some reason it just drops right to the floor. lol

Any input or advice on this type of workout? Do you think it's worth it?
