I joined the cult of the Instant Pot a couple months ago when the plastic housing around the steam valve on my 10-year-old Fagor pressure cooker cracked. Based on recommendations from a lot of people, I bought an Instant Pot to replace it. I've been very happy with it. It's even more foolproof than the Fagor. It is a built in slow cooker, pressure cooker, and rice cooker. It also makes yogurt but I haven't tried that feature yet. I've used it to make dozens of one pot meals: curries, sweet potatoes, squash soup, zucchini soup, and so on. There are lots of cookbooks written exclusively for Instant Pot, too.
Today Amazon is selling the 3-quart Instant Pot for $56. A good deal!
