I hear yah... I don't even buy the Ace Hardware blades... They lasted pretty good, the teeth wouldn't wear off. But the offset of the teeth would go away and they'd start cutting reaaalll slow. I started buying Milwaukee blades, and they cut all the way up until I break em. Or until I try cutting some stainless.

As for HF, We've got an impact wrench that we got there that's been used regularly, (but not occupationally) and it's still going strong. But, from the outside, it's identical to the Ingersol-Rand that sat on the bench right beside it... Gotta wonder sometimes.
Some HF stuff is crap, some is surprisingly good. It's a toss up. If it's something you want to last awhile, buy quality. If it's something you only need for one job, go for the cheapy...
