New microwave - turntable or flatbed?

[cozietoesie]

My current microwave - an older turntable model - is starting to show some signs of frailty and I may have to acquire another at fairly short notice. (We use it a lot.)

Given the large price difference and the fact that if we have to have a new one, we'll likely be stuck with it for a good while, I was wondering in particular whether it's worth investing in a flatbed model.

Does anyone have any microwave recommendations?

I use mine for grill, convection and microwave. To clean I just wipe it all with a cloth, I don't do much with the grill other than wipe it.
I also microwave a small bowl of water with a squirt of lemon juice for a few minutes so steam it up before cleaning it.
It doesn't need much.
