I love harbor freight, they have cheap stuff but if you only use it a couple times its worth it.
I love their black impact sockets. I've broke a few craftsman but am unable to crack one the theirs.
Air tools are pretty good, I have the cut off wheel, air saw, and nail gun. All work great.
I've actually never had any issues with any of the stuff I bought from there.
My greatest investment there was the $400 tool box. I would say it falls in between a snap on and craftsman. Very durable and VERY impressed
I'm in it for a ground pounder. Screw the meter!
