Best curling iron for black/african american hair?

I’ve tried a cheap one (about $10) and it didnt work AT ALL. I have VERY thick VERY stubborn hair. I’d like one thats not too expensive, I’m not paying a cent over $85. Preferably a ceramic one, too.

PS: Please dont say black hair is the same as blonde or red hair, or that race doesnt matter. That’s just ignorant.
