Where can i find a little crock pot (about 16 oz) with a temperature control?

I am looking for a very small crock pott that has a temperature control. All i can seem to find is the Rival Little dipper crock pot, which is the correct size but does not have a temperature control on it. Does anyone know where i can find this product or if it evenexists?
Update: when i say temperature control-the high, med, low options are the temperature i am referring too.
