I have flea mkt tool tent where I flip a lot of "cheap tools" small name import brands mostly so I get to try a lot of them out. Honestly something like Great Neck Deep CRV impact I have sold are dirt cheap and have held up to lots of abuse from me (non commercial work) with all my different cordless Milwaukee impacts... Stubby, Mid Torque, High Torque. haven't broke any doing truck and tractor lugs.
But by far my favorite "cheap set" is the 37 pc HF impact socket set also a CRV and I use that often because of the case. It's so convenient to carry to my jobs out in the field or take in the vehicle. No problems with them either and I do think they are better sockets than the Greatneck. Less than $25 on special with coupon usually.
I also have the Pittsburgh 1/2 drive shallow sets both metric and standard they seem to be thicker wall construction than any of the others also a dull finish. And not at all the same as the 37pc. Can't beat them really. What are they $10 on special I think.
Also have a set of cheap CRV impact sockets from the Tractor Supply Store around. JobSmart brand I guess it is, seem no different than the others really. CRV construction, its a little case a mix of shallow and deep, weird thing about them was the sizing. Never really use them tho. I picked a few of them up for $5 each to flip over at my market and held one back for shits and grins.
My best sets though are Cro Mo 3/8" drive, I bought thru Eastwood some years ago full sets in nice storage cases, shallow and deep, metric and standard. Though Eastwood sold them the packages say Apex Tools on them.
