Kalustyans in NYCmay have some.

I received one as a Christmas gift this year. I believe my friend bought from the Turkish goods vendor in Chelsea Market in NYC.

Check on 3rd Avenue near 28th Street. You should be able to find something with little effort. You might also consider an earthenware tagine which functions pretty much the same way. I'm big on clay!

Clay pots are readily available here in the US. I have a couple myself! : )
