I have this instant pot, which I highly recommend. It goes on sale fairly often. Which $38 cooker are you looking at?
It's a good size for me. I'll often use it to make a large batch of food all at once, then portion it out and eat it for the rest of the week. Saves a lot of time overall, not sure I could do it with a smaller pot.
There's also the Lux "6-in-1" that is I believe is similar, but notably missing the yogurt/fermentation options. I personally really like those options so I wouldn't get it, but thought I'd mention it at least: https://www.amazon.com/dp/B006E7I7MG/
