Thank you to all of you who replied. I have decided to buy a Beko from Aldi as I have other Beko products and the microwave was on offer. It also looks like the one I am replacing. Someone kindly mentioned Aldi but I cannot find the message.
Always Panasonic for me - very good quality. I don't buy the type with the grill/oven facility as I doubt I'd use it, I just need a basic microwave. I always choose the large capacity too - 27 litres or more, and a digital control panel - more precise than the dial type.
Mine is a cheap one from Asda. Cost about £30. Manually set the time and manually set the temperature i.e. Defrost etc. I use it every day. It's 12 years old and looks like new. It's exactly what I want. However I do use my main oven most days also.
ASda do a decent range of different microwave machines, from £40 up. They all seem to go rusty after a while whatever you pay so I don’t see the need to pay a lot more. The first one we bought 40 or more years ago cost ten times as much, which highlights just how much cheaper these items are now. Basically they do the same job so can’t advise other than go with your budget ( but you will be hard pressed to find one costing £400)
We have a basic microwave as we only use it for quick jacket potatoes, warming things up etc. It was from Aldi, £49 I think and it's fine. Does the job.
For some years I have had a combination microwave oven with a grill and ‘proper oven’, bit more expensive but I only use that now,does everything ,baking, roasting , grilling. I don’t use my big oven except for larger meals, seeing we don’t have any visitors now this is ideal for two of us.
I need to buy a new microwave as I overcooked something by mistake causing a dish to break and flames inside. I have looked online at recommendations but there are so many I cannot decide which is best for me. Any suggestions welcome.
