Up voted for basic commercial unit recommendation.
I have one of Panasonics upper model flatbed microwaves that also acts as a fan forced oven with traditional oven element and fan, and as a grill with two overhead halogen grilling elements.
I picked it up for 50% RRP as it marked down for a minor defect I can’t even recall.
It’s 1900 watt on full microwave power, if I recall correctly, where most on the market amend here are 1400 watt. Makes a lot of difference, browning the top of food is easy with a bit of oil.
I can’t really fault it, it’s super easy to keep clean and works great for baking where using full size oven is overkill.
