Say you were just starting and wanted to upgrade your shop game. What would you get first? What has proved most useful?
I was thinking my air compressor really isn't up to much more than airing up tires. I also don't have a HVLP sprayer. I was thinking a 20 gallon with enough CFM.
I've thought about a small welder. But then, I'm not a welder and wouldn't weld anything of importance (like a frame). In the cases I wanted one, it was for a spot weld. So maybe not an overall useful thing.
What else?
