No-one is holding a weapon to you and making you buy one. If it doesn't meet your needs, or is more expensive than you want to pay, buy one that meets your needs, or that is within your budget. That's why there's numerous models and levels of functionality and finish on the market, at different prices.
Same with the OP. Nobody is making him keep using his HF wrench. He gave it a fair try at 3 times, and wants to move on. He's asking which one would be an upgrade from the one he had fail.
I'd look at it exactly the opposite. I've used the Snap-on ones, other quality flex heads, and the cheap ones. No way does saving up to $100 or even a bit more justify having to use the cheap ones. I don't miss the money I spent getting the tools I have now, but do appreciate that they work the way I want them to every time. That doesn't detract from the experience of the guy that's perfectly satisfied with the performance of whatever wrench he has, that's not the same as mine, either. If it's working for him, and meeting his financial objectives, that's excellent. The only situation that I feel some sympathy for is the guy that has something that isn't meeting his needs, but isn't able to buy better because of some financial ill circumstances.
