We have at least two "crock pot" slow cookers, but they're seldom used.

My preference is an older version of the Presto Multi Cooker, since you can yank the control plug out and toss the whole thing in the sink or dishwasher.

The control setting dial indicates degrees F, and is apparently quite accurate at least near 200F, since you can "nudge" the setting either side of where a visible simmer appears. And it's close enough to deep fry small batches without using a separate thermometer. (We don't keep enough oil on hand to fry big batches.)

Note that ours is an older version, without the "temperature indicator" that appears to be shown at the link.

The current add shows a price at about $40 (US) but I saw a couple marked down to $24 a couple of days ago that I think were the same model.

I don't particularly care for the "non-stick lining" but it's becoming almost impossible to get anything without that #@$!% crap on it. My current one has lasted about 14 years without losing too much of it in the food.
