I get the point about keeping gas in the event of power cuts, but I think I fancy trying an induction hob.
There are two kinds of people: those who love induction hobs and those who haven't tried them yet.
OK, so maybe a rash over-generalisation there, but we've had an induction hob for 15(?) years and you couldn't persuade me to go back to gas.
The camping stove does the job for us when we have power cuts. You just have to recalibrate your dinner expectations slightly (much like you do when you're camping, in fact). We once had a power cut that lasted a whole weekend and lived to tell the tale. Such is the amazing resilience of human beings.
Also contemplating replacing our 30+ year old microwave with a combination one.
I also love our combi. It's surprisingly versatile. One of the best things about it is a proper crisp-skinned baked potato can be done in 20 minutes instead of an hour. (Yes, you can cook a potato in a microwave in 10 minutes, but what's the point of a baked potato without the crisp skin?)
