Hi John
There is a oven that Alto Shamm also makes that is a cook and hold oven. You can put the roast in the night before and it cooks and holds it for the next day.
My personal problem with these are they use such moist heat, there is no crispness or caramelizing of the roast.
The Combi has a option for no moisture which I like. But being so old school the younger chefs seem to like this better. As they like stacking, poofing, squirting sauces and micro greens.
Personally I like a plate of food these days. Not something that costs $38-$60 dollars and I can barely tell what I am eating. Then when I get home, I am scavenging the refrigerator for something to eat as I just paid dearly and disappointed for 4 oz. of something I had for dinner that barely satisfied my appetite. Then get really upset as I could have bought groceries for almost a week that I just spent on "dinner". ; )
