It has been discontinued, however you can still find them on Ebay and places like that. I just purchased a brand new one on Ebay and it cost me about $45.00 (including shipping) on a buy-it now. Some of the ones that are actually being auction off are running between $25 and $60 (including shipping). There are also several used ones available, but the price seems about as much on them as some of the new ones. Go to eBay and type in "Rival Indoor Grill" in the search field and it should pull them all up.
Contact Rival via telephone, internet, or snail mail.

Almost any recipe can be modified to use with your crock pot, that's why crock pots are great. Crock pots can be hard to clean, but if you use a liner it is much easier.
A crock can be kept in a freezer without any problem, if that's what you are wondering.

From Wikipedia: The Naxon Utilities Corporation of Chicago developed the Naxon Beanery All-Purpose Cooker. Rival Industries bought Naxon in 1970, and reintroduced it under the Crock-Pot name in 1971.
There are several books available for the rival slow cooker. Rival Crock Pot: 3 Books in 1: Slow Cooker Favorites/Winning Slow Cooker Recipes is probably the biggest one out there. Another great one that is available is the Rival New Creative Crock-pot/slow Cooker Cookbook

The temperature settings on a Rival Crock-Pot are listed by increasing temperature meaning that the high setting is represented by the higher numeral and the low setting is represented by the lower numeral. So, "I" means low and "II" means high.
