I just thought I'd add to this,
My parents had a Tricity president cooker which they purchased second hand, my mother loved it. I can't tell you much other than she liked that it had a fanned main oven, spiral rings and one of them could be adjusted to the size of the pan you were using, and also the grill had the ability to have half of the element isolated if you were only cooking small amounts of food. My mother replaced it because it was starting to head on its way out in 1996 (I think) with a basic Creda electric cooker, which she hated. The Creda featured four solid plates, and a traditional non fan assisted oven, she didn't like the hob which she found very uncontrollable and likened it to cooking on my grandmothers Rayburn, it was very easy to burn food to the bottom of a pan or for a pot to boil over, she also found the oven to be a bit hit or miss and slower than that of the Tricity.
The Creda got put into a flat that my grandmother used to let out in 2000 and my mother purchased a new cooker. She purchased a Tricity Bendix Strata cooker with a ceramic hob, fan assisted oven and catalytic liners as well as a grill which doubled as a secondary smaller oven, and this cooker was simply fantastic and very well made, I learned to cook on it and its made many a Christmas dinner and birthday cake, the cooker still works and we gave it to my sister in 2016 when her Indesit cooker (very basic solid hob, traditional oven) broke, we then upgraded to a Belling FSE60DOP cooker in stainless steel.
The Belling has a ceramic hob with one zone that you can use half of if you are using a smaller pan, a grill which you can isolate half of and use as a secondary oven, and a multifunctional main oven.
The overall cooker is pretty solid, however I think that main oven is very difficult to clean because of the multifunction aspect; the oven has the following functions: defrost, fan, base heat, top heat, base heat and top heat, base heat top heat and fan, grilling and fanned grilling. Because of the grill element, its difficult to clean any splatters in the roof of the oven, but overall its a decent oven but certain aspects of it, I do think our last cooker was better.
Sorry that was so long winded
