An example for not producing anything themselves (afaik) but only putting their name on actually decent products is Blitzwolf. A brand like that can be built on the most basic due diligence (and thus not significantly higher prices). A bonus would be actually delivering some technical detail on a product, but even "manufacturers" like TaoTronics seem to be having a really hard time doing that.

I'd say Aliexpress is probably a better way to find somewhat established (or trying, which is what matters) brands than Amazon.
