I recommend buying the following pressure cookers while you're in the US:

https://www.amazon.com/Magefesa-01OPPRAPL47-Practika-Stainless-Pressure/dp/B00OQ2WFFG/ $85.99 for 4qt+6qt. set with steaming basket, trivet, and glass lid. They share the same pressure lid.

https://www.amazon.com/V-2L-Stainless-Sandwich-Pressure-2-Liter/dp/B00EYZT85K/ $35.71 2L pressure cooker.
