I bought my first one years ago, and the non-stick wore off pretty quickly. I was still able to use it with a lot of work. I finally got another one for Father's Day. It is working great, but I would like to be able to purchase additional plates for my original. I would like to run both when making my waffles. I clicked on the "parts" link, but it took me to a powertools servicenet place. Where can I get replacement plates?
