GSI makes a halulite pressure cookers are light and discontinued, but still fairly easy to find…
I chose to purchase a high quality pressure cooker that has zero compromise. I think Kuhn Rikon and Fissler are the two best brands. I went Kuhn and love it. I bought a smallish one (3.57qt) with small handles, but it is still rather bulky and heavy… I love it anyways.
If you like a lighter one hit up TFal or as Chet6.7 mentioned Presto.
If you have decent amount AC power Instant Pot has some small devices that work great. We had one at home and I loved it.
