I feel that a lot of people are stuck in cheap furniture, because they either do not know better or just can't afford anything better. Both of them good reasons to learn to do simple repairs. In any case it is good to not produce more waste!
Good luck with your project. It sounds a bit more intensive but I'm sure it's doable!
I've had 20€ kettles that work for years and and 20€ kettle that break once the warranty is over. Cheap electronics are a gamble. So is expensive ones, but I feel that with those you can at least try to find a trusted brand.
