I bought this years ago because my grandmother had one.  She had the best. (including the B&D Toast R Oven which ROCKED!)  Used it about a dozen time to make the kids waffles.  Each time, the sticking would get worse.  I would always hand was the plates.  This last time, I brush oil in the plates and it was still a disaster.  Where can I get new plates??...preferably cast Iron.
