Harbor freight sells three tiers of many of their more popular tools and they're not shy about it. Most of their signage says "ok/better/best" and they're very transparent about what you're buying. I can buy a $9 angle grinder and on the same shelf I an also buy a $85 angle grinder, with the "better" model running ~$25-40. Harbor Freight used to have exclusively cheap junk but their "better" tier stuff is more than adequate for home DIYers

It probably helps that the founder is still the owner. Once that guy or his son dies (he's getting up there) it would not suprise me if the brand spirals into decay.
