This Presto pressure cooker works for my needs.  When I recently had to replace mine I looked at the more expensive versions but simply couldn't justify the added cost.  The one I just replaced was over 10 years old when I replaced it, if I bought one that costs 5 times as much then it would probably last at least 5 times as long - but I do I really need a pressure cooker to last 50 years?  I use it as a pressure cooker several times a month and use it as a general purpose type pot a few additional times a month.  It isn't exact regarding pressure, but let's be serious, neither is most cooking in general.  If you need to know the precise pressure for some reason, then I wouldn't recommend this one.
