I buy stuff I'm only going to use a couple times from them. I also buy tools that I'm going to modify (bend, gut, grind) to make specialty tools. I hate doing that to good tools.

I would not buy something like a compressor from them.

 

I bought a harbor frieght compressor about 3 years ago for about $89.99. I bought it because my compressor was in the shop. I've been using the dogmeat out of that thing and it's great. Doesn't have a high enough output to run an impact or hopper gun at full trigger but it's great for nail guns etc. I rarely use my other compressor anymore. The harbor freight compressor is small and light and easy to load. My other one is just for big stuff.
