I presume you're talking about the first stove in the linky.
Have to say that - pragmatically - they're excellent value, and remarkably fast and easy to cook on - good heat control, lots of it, and I've always found them very stable. (I've also got one - slightly larger - but with a "skillet-style" top you can add on - Robert Dyas sometimes has them in) Gas canisters are cheap and readily available. Not a sub-zero cooker to be fair as most cylinders are butane, but that covers most of the year in the UK! Not a long-term investment as they tend to be built of cheap materials, but for general ease of use (slot in cartridge, turn gas on, click the ignitor in the rotating control and off you go), they are excellent.
However, not as much fun as many other cookers, which get you more "involved" in the whole process. Can't beat a bit of pumping, priming, and general messing about with a good liquid stove, or brewing up on a coke-can stove you've built yourself out of a beercan or two!
