That's the sort of thing I would like but I really don't have room. The negative reviews, by the way, are in the minority, and in such cases, I usually suspect that the critics simply haven't read the instructions properly. I used to use a pressure cooker loads, but haven't for a good few years now.
The first one I had was a Prestige which I got as a wedding present. If I replaced the gasket and the safety valve, it would still work today, but it was an aluminium pan, which we now know is not very good for you. The beauty of it was the simplicity - it was just a weighted stopper on a little spout. For years I tried to get one with a stainless steel pan, but I've managed for ages without, and don't think I really need one for just the two of us, especially as my husband isn't keen on one-pot dishes.
If you are sure you will be using it at least once a week, and that you really need it for a small household, I should go ahead and get it - it certainly looks tempting!
By the way - did anyone watch the video on the page that was linked to? It was just a girl talking and waving her hands about over the cooker. What was the point of that? She didn't even take the lid off, let alone demonstrate any cooking techniques with it!?!
