How do you buy random electronics gadgets these days?

There’s got to be something *useful* between “I know the brand I’m looking for and a store I can buy it from” and “Um…there are 523 virtually identical items on Amazon, each with a different randomly-generated 6-letter ‘brand’ name and 50000 reviews that may or may not be from real people or for this actual product.”

Sorta thinking if it’s going to be junk anyway it doesn’t matter which one, but also thinking that’s the whole business model and I’d rather not support it.
