My only comment is make sure the cooking vessel of the "insta-pot" is not nonstick, but only stainless steel.  That's why I'd only select the real thing.  I want one, but still have other financial needs first.  I miss my PC since I got my induction range.  

A friend of mine was intrigued by pressure cooking but was scared to death of the device required for it even after I offered him one of my Prestos and gave him a demo using plain water.

A local ACE Hardware was closing and I found a discounted instant pot there, so bought it for him as a birthday gift.  That was over a year ago and he and his partner have been using it regularly ever since.  They love it.   Do be advised that the instant pots I've read about tend to cook at a maximum of 12 lbs. of pressure rather than 15, so some cook times will be a little longer.

That Aldi price sounds like an excellent deal.  I can't speak to non-stick vs. stainless or really anything else about instant pots.  I like my vintage Presto and Mirro cookers too much and don't see myself owning anything else.

If it's anything like my inexpensive older electric pressure cooker, then buy it. I'd never use my two stove-top cookers unless I needed another pot for something, although I know people love them.

Kinda confusing digital control, but the price was right. Online seller (Overstock.com) sent me red instead of white, so they refunded my money and said "just keep it".

OK, sous vide has attracted my attention.  My surrogate/frequent housemate has raved about sous vide, although I don't recall what the dish was.  I may have to cave, even if it means dealing with an annoying electronic touchpad.  His birthday is coming up.  Maybe I'll buy it for him so he can assume the role of sous videur in chief.

I have had mine for years, on my second one actually.  My first one was smaller and I wanted one that was bigger so I can make a big pot of soup at one time.  I use it mostly for soup and have tried a couple of other things but we didn't grow up using one so I never really had foods cooked in them.

My niece has the Insta-Pot and she raves about it but she never had the Electric PC.  Are they that much different?  

I have several stove top PCs but I really like the Insta-Pot for the delay and keep warm functions.

You can "set and forget" it. 

Typical usage:  I come home at 3:30 to get my daughter off the bus.  Realize I forgot to put a roast in the crock pot that morning.  Put the roast, potatoes etc in the Insta-Pot, set it for 90 minutes and go back to work.   When I get home at 5:00, I release any remaining pressure, check for doneness.  If not quite tender, put it back up to pressure for desired time.  Bringing back to pressure doesn't take long because everything is already hot.    In worst case, still serving dinner by 6:30.  If we aren't ready for dinner due to working outside etc.  It will automatically keep everything warm.

I do have a stainless steel insert, but hand wash because it takes up so much room in the dishwasher.  In any case, usually just that insert/pot to wash up afterwards.

This is the main reason I don't use mine more.  Seems some things can be cooked on the stove in the time it takes for them to come up to pressure and then cook in the PC.  For me, I think the other thing is we never had one growing up.  I don't know why my Mom didn't use one as I never asked her.  I suspect her Mom never used one either and she probably learned to cook not using one as I did.

I got the 8qt model and the optional stainless Steel insert. 

Mine doesn't start counting down the cooking time until it reaches pressure.  So if I set it for 30 minutes cooking, it cooks for 30 minutes under pressure.  Then you make the decision based on the item inside if you let it naturally come back down, or vent the pressure. 

Neither of these aspects bother me that much when I am using the "set and forget" delay and keep warm function.   The pot is programmed to start the cycle a few minutes early so that it actually starts cooking at the programmed time, and the keep warm function allows for natural release of pressure, hence it is ready to open and serve when I need it.

Large items, like  roast, usually benefits from the natural release, whereas items like vegetables will benefit from a quick release, venting.

My seal is inside a wire spider that snaps to the lid.  It's approximately 3/4 of an inch thick silicon, and holds it's shape very well in the sink, even removed from the spider while washing.  It would never go down the disposal unless forced through the hole.

When I got home from the grocery store yesterday morning, I noticed a box on my front porch.  I wasn't expecting anything.  I opened up the box and someone very special  to me (a fellow member) had sent me an Instant Pot 10-in-1 Ultra 60.  I was overwhelmed and called him immediately to thank him for his generosity.  Today I'm going to make some brown rice to go complete my red beans & rice for lunch.  Yesterday I also got a 2 pound boneless chuck shoulder roast I will cook today too.
