I realise it's the opposite of what you're asking, but:
Honestly it doesn't really matter what it is, if it's something you are going to rely on, don't cheap out on it if you can afford not to.
Pretty much every non-consumable product category has a low end of cheap shit that is not worth anyone's money.
Also, and this only really applies to big electrical items: if you can be bothered, find someone who repairs the kind of thing you're trying to buy and ask them what the best made brands and models are. They are the people that will know better than anyone else what is built to last and what is built to be replaced when the warranty expires.
