Like alot of others have commented here, I find Harbor Freight is a mixed bag of pretty good stuff and poor quality stuff, so you have to do your research online. The good stuff I have includes their pedestal fan, 20 ton shop press, Daytona floor jack, creeper, welding cart/cabinet, quick-release bar clamps, and the Titanium Flux125 Welder, which so far seems to be a good value for a beginner's welder. For anyone considering getting into welding inexpensively, I have a video on the Titanium Flux125:
I also have a Bauer SDS-Max rotary hammer drill which has held up surprisingly well after heavy use, and recently got a chop saw, but too soon to pass judgement on it.
One disappointing item is the 10 pack of #2 Phillips insert bits. They wear down quickly. Also, I don't buy their blades, based on YouTube review and performance tests.
