Pressure Cooker suitable for traditional Indian dishes, available in Europe
I don't see anything "special" about that recipe that depends on the particular pressure cooker. I don't think you need anything fancier than an old-fashioned pressure cooker and a timer, assuming you know how to use an old-fashioned pressure cooker. If you already own one, why buy another? 

Figure time on "high" to be time on 15 PSI (or 1 bar) steam, and cook away.

A brief glance at the link shows a thing that seeks to be everything (pressure cooker, rice cooker, yogurt maker, really should have Ron Popeil do ads for it on late night TV...) some of which would be more difficult in a regular pressure cooker, though (for instance) we had a spot on the stove over a pilot light that could make any pot into a yogurt-maker if you set it there full of milk and culture. And you can certainly make rice in a pressure cooker under pressure, rather than trying to mimic a "rice cooker" at atmospheric pressure.
