We have a 10 year old 90cm Rangemaster range cooker with a ceramic hob. It was installed new into our new (at the time) kitchen extension. We were looking at putting in an actual Aga/Rayburn at the time but the running costs didn't add up so we went for the cheaper and more energy efficient option. Love the ceramic hob on mine, is easy to clean and still looks as good as new. The cooker is still going strong and we have never had any problems with it <touches wood>.... HTH
Just been back to the shop to look again and they have a 90cm induction range which is the Professional + one...less than half price.
I don't know what to do - kitchen will be a little more cramped with the 90cm one, but I saw the grill on the 60cm and really didn't like it - the pan scrapes on the bottom of it, and you can't shut the door without putting the grill pan on the floor, handle inside the cavity.
I don't fancy having the grill open all the time with a handle sticking out till it cools down.
I'm stuck - I don't think I can change my mind and have a refund on the 60cm one, because I bought it in the shop though I didn't see it as it was packaged.
They will let me buy the dearer one of course instead!
