This is my first pressure cooker and I really like it.  For this price, it is a good choice for those who aren't sure if they will use it much.  It is especially useful for vegetarians.  Beans that normally take 2 hours to simmer in a sauce pan are done in 20 minutes in the pressure cooker.  I was afraid to use it at first but there are safety features which should make you comfortable using it.  As long as it is under pressure, you cannot open the top.
