I decided to buy a pressure cooker. The initial research showed that I had to choose between electric and stovetop. The stovetop is better, but it makes me nervous to leave an unattended stove, so I picked electric.
The first review websites I ran into showed the Emeril CY4000001 ($120) and the Cuisinart CPC-600 ($100) as the two best units. The Emeril was a little better because it did not lose as much liquids from evaporation, but the difference is small (3% vs 2% or so). Now the Cuisinart can be found in local stores, but the Emeril has to be bought online, and it actually seems to be out of stock in some cases.
Then I found the “Instant Pot”. Made by Canadians, and the reviewers say the company is very responsive and always improving the product. You have to buy it off amazon, and it can be delivered for about $130.
Their current model is the Instant Pot IP-LUX60, but check their website at Instant Pot.
So either get the Cuisinart from a local store or the Instant Pot from Amazon. I went with the cuisinart because I wanted it now. Got it from Dillards.
