I'm ready to buy a pressure cooker and I'm looking at the Kuhn-Rikon Duromatics. I'm not sure which size to get, though. I'm mostly cooking for two, but I like having leftovers, and I'm concerned a 4-qt one won't be large enough for larger proteins or stock (which, in reality, I probably won't be making all that often). I'm leaning towards one of these three:

Because they all look fairly similar, this is rapidly becoming the most difficult decision I've ever had to make. Does anyone have any advice?
