I've been looking for one as well and cannot seem to find one with a timer that you can set for a delayed start. Likely, as a pp mentions, due to food safety issues. Which, when you think about it is a complete joke. Unfortunately, makers of such products truly believe that most consumers are stupid enough to throw a chicken in a crockpot and set a delayed start for 3 hours later. When, in reality, I could throw a few frozen chicken breasts in, set a delayed start for 3 hours later and be perfectly fine. The problem is that some fool would let something sit too long, get sick and then sue the crockpot maker because the delayed start option was a bad idea.
Yes, all I wanted was a crockpot with a delayed start timer. And, I am bitter. ;)
