I grew up where my working step mother cooked many of our meals with a Presto Pressure Cooker out of time necessity and always enjoyed them and I don't know why I put off buying one for myself after all these years.  Not only does one of these cookers greatly reduce your cooking time, they also save you energy as a well.  So far I have prepared beans and ham soup, a clone recipe of KFC fried chicken and savory pot roast in my unit and the food has been delicious.  This unit comes with a very basic cook book but Presto offers a large cook book for $19.95.  I have found many delicious pressure cooker recipes on line by using Google for "Pressure Cooker Recipes", including the savory pot roast recipe that I just tried and the KFC clone fried chicken recipe that came out moist and tender. Where it normally took me all day to cook a pot roast in my crock pot, this unit did it in just at one hour and the roast was fall apart tender with a rich and tasty broth.  This allows you to use less expensive cuts of meat that you can catch on sale like chicken leg quarters, chuck roast, ham and beans or any lentils for that matter.  All at greatly reduced cooking times and resultant less energy consumption on your electric or gas range.
