We seem to get through cheapish microwaves (£40-£60) at the rate of one every 2 years due to the inside (under the turntable) bubbling and cracking.
The only ones I can find with stainless steel interiors are pricey all singing, all dancing ones when really all we need one for is warming things up, defrosting and the occasional emergency jacket potato.
Has anyone got/seen anything suitable?
