Help with finding an oil diffuser?

I’m looking for oil diffusers that have either a ceramic or porcelain topper. I’ve been looking all over online, but I can’t find a good website – so is anyone willing to help me? Can someone point me where to go?

Here’s an example of the kind I’m looking for (I don’t want a diffuser meant for reeds): http://www.bobbyberkhome.com/product/candles/20845/blissliving-home-kafir-lily-flower-diffuser.html

It doesn’t have to be identical, or even have a flower topper. I just want a glass bottle, and porcelain/ceramic topper. Thanks!
