I'm addicted to pressure cooking! I have several units, b/c I scored some great deals and b/c if one of them goes, I didn't want to wait for another good deal, as I use mine at least 4x/week.
I didn't buy into the InstantPot craze, so my first unit was a GoWiseUSA 6 qt multi-cooker, that is still going strong 7 years later. Purchased for $60, shipping included, brand new. It has a non-stick pot, which was great up until a few weeks ago, when I noticed what looked like peeling, so I replaced it with a stainless steel liner I had scored a deal ($12) on a while back.
I am loving my latest purchase, which is the Insignia 6 qt model, available today at BestBuy for $30 - and it goes on sale for this price very often. I've purchased several of these units at that price for friends, and they all love it as much as I do. From what I've read, it's made in the same factory as the InstantPot, and it looks nearly identical to one of the older models (Lux, I think?). It does have a non-stick liner, but I prefer that option.
Btw, I've done head to head competitions with both units, and third off-brand model I scored at Home Depot for $20, and all three of them do the job perfectly. My test was brown rice, and all three units delivered perfect brown rice at 22 minutes, and their timers were all very very close, no more than 30 seconds apart. the only reason I don't recommend the off-brand Home Depot unit is b/c of poor design - I don't use any of the auto buttons, I just select my times to cook and go - and this model only has an up button, not a down button, so if I'm making hard-boiled eggs, this unit defaults a 30 minutes, and I have to go up to 12 hours before I can get to 0, and then set the cook time for 6 minutes. Not a huge deal, but really, stupid design!
