Plenty of good choices out there guess it all depends on what you need and what you want to spend. Both Sunex and GearWrench offer really inclusive sets. Cant go wrong there
So just as FYI I did buy an SAE only impact set thru Eastwood to carry to my daily job for use with my original 2463 3/8 impact purchase so I wasn't splitting up my garage tool sets and I use it often on other impact drive tools too including my M18/M12 Fuels both sq. drive and 1/4 hex.

Overall it is a decent set for the money Cr Mo and has both shallow and deep up 3/4" and a solid storage box and they have held up well for me. Markings are only printed and aren't stamped though. (edit: they are stamped on the opposite side). No idea of OEM on it and of course it is import. Anyways first time buy is another 10% off too. I may have bough it on a percentage off sale too don't really remember now.
I would have liked to have gotten the metric offering too but its more money I and I don't think its that great a deal
Cheap being cheap a guy may grab the HF 68011 right now. With a coupon its only like $25.99, and get 3/8 and 1/2 drives in both metric an SAE sizing.
I have been contemplating getting one just to toss in the work truck.
Now can't vouch for the quality on that set the only impact rated Frieght stuff I bought was some metric deep 1/2 so long ago that they came in steel storage box and very recently some extension bars both 1/2 and 3/8 wasn't overly impressed with them to say the least .
Maybe someone will do a followup question in a different forum on that set
