Where can I find an automatic coffee urn?

Actually, you can probably find one right next to the ice machines in your supermarket. I saw some when I was shopping at Wal-Mart the other day, so you should check there.

I have found a great one for you at a great price. The Coffee Urnd From West Bend, makers of coffee-related products, comes this elegant urn made of highly polished aluminum. It holds 30 cups making it ideal for the office or at home where you can allow guests to serve themselves. A serving light and interior water. I also like the Saeco Renaissance.
