I bought a big set of 1/2" chrome deep 6 pts. off of amazon about two years ago. They were Taiwanese, and they are very nice. I haven't used them enough to declare that they do or do not crack when going after the stuck-est nuts, or that they round off bolts or not, but my general impression of them is that they're very nice, like much from Taiwan anymore.
The markings/number size on each socket wasn't rolled in with a stamping press type operation, but a lot of little dots, presumbly with "laser beams." It's okay. It's not
great, but we all know what brands to go to for that.
I paid $66ish, plus $10 shipping. Price is a little higher now. Still a very good value.
