Here's my list of 10 items that you should only purchase from Harbor Freight Tools. I can vouch for all of these tools as a jack of many trades, and can say that there is no need to spend a lot of money where it's unnecessary.
Harbor Freight is the best place to buy good tools at affordable prices. Pay attention to the prices that I list from Home Depot and especially MATCO Tools. How does anyone afford that stuff? Yikes.
