I could absolutely be wrong. As I said, I don't really collect tools or review them in any real capacity... BUT, I would never consider buying foundation tools at Harbor Freight - even if I was limited by budget.
I think you're definitely wrong. There are plenty of people out there wrenching every day and earning money on tools from HF. And while the finishing on P-Pro stuff is often a little rough, I can't recall one coming up as a FAIL in one of the biggest threads on this forum. For the most part, they're fine to good. The Icon line as a whole is good (there are a couple exceptions that are only fine) and goes all the way up to excellent.
I don't earn money with my tools, but I use them enough and have a mixed enough set of things that I think I'd see the bad spots (e.g. my Icon ratchets vs. my Tekton and Snap On). But I don't

I tend to reach for the SO 3/8", but still prefer my Icon roto 1/4" to my Snap On.
I think it's a travesty that one of the first thing that seems to happen to most guys who enter the profession of being and auto tech is they're sold a bill of goods that they need hideously-overpriced box full of very expensive tools. It's just a payment, right? They'd be far-better served by getting a USG box and a bunch of HF wrenches, ratchets, sockets, etc. and put that $25-$50 a week in a freaking IRA. (Other than the box, you could substitute Tekton or even Napa Carlyle in that sentence, but whatever).
Harbor Freight is still trying to live down the **** quality they delivered 20 years ago, but these days their core tools deliver pretty damn good quality. The Icon and Doyle lines are (overall) a healthy step up from that. Their power tools line is flawed mainly because they have a terribly battery platform/portfolio, but there's a lot of value-for-money in the basic lines (though there are some stinkers), but there are generally at least two more tiers to go up for better quality/power/features/whatever. Even AvE gave a fair amount of love the the Earthquake impact a while back for quality of design, components, etc.
I'm not an HF flunky, but I'm also not holding any grudges from a couple decades ago. I choose tools carefully, and have a lot of non-HF brands in my (USG

) cart and box, but I'm not unhappy with any tool I've gotten from HF. :dunno
