I own a cheaper Craftsman set and a nice Snap-On set. They both break, especially if you go too fast with the taps, or use them at the wrong angle. Removing a broken tap can add hours to your project. I'm not convinced that any of the high priced sets are better than the mid-priced sets, but as much as I'm a fan of Harbor Freight on some things, I'm not sure I'd gamble on the their tap / die sets.
knowing how to use the taps is 1/2 the battle. Lube, keep it straight, and break the chips. If I can, I tap in a drill press or lathe (not under power) with a centering tool to keep the tap straight while rotating the tap by hand. If I'm tapping by hand and can't use a machine to keep the tap straight, I usually use a make-shift tap guide (tubing welded to flatbar, or holes drilled through thick metal or tubing), that helps a lot to get the tap started straight.
I also try not to ever start taping with a bottoming tap. if I need a bottomed hole, I'll get it started with a normal tapered tap, then finish it with a bottoming
