I have not re read this entire thread... But your going to love it.Call it Covid - 19 retail therapy.
My first Instapot arrived today. 3 quart 9 in 1. It falls in between the size of two non-electric pressure cookers I own. I have a suspicion over the ability of complex electronics to endure but I am pretty impressed by the thickness of the stainless steel inner pot. Just ran a steam cycle to start to get rid of the new smell . . . oils and other stuff from manufacturing that needs to be gone before I cook with it.
I've reread this whole thread and I've got some ideas.
