I was in a similar situation, a nice new ½” impact wrench and no suitable sockets.
I got this mainly for lug nuts, so really I just needed a 19mm, but I wanted a few other sizes as well. Even the HF sets add up quickly $$ for metric plus SAE and I just couldn’t find a good solution there.
I ended up with a Campbell Hausfeld set from Wal Mart of all places and so far I like it even though I’ve used it just a few times. It’s a mix of both MM and SAE all deep sockets for $20.
They look pretty nice with both large white and stamped markings. Overall, this set just looked much better than anything I could find at HF and it comes in a nice plastic box also. 11 sockets total…
Metric: 13, 14, 15, 16, 17, 19
SAE: 1/2, 9/16, 5/8, 11/16, 3/4
