I have a Central Pneumatic compressor. It seems to work just as well as my last compressor. It was a Craftsman that I paid 3 times as much for.
Actually, I but a lot of "junk" at Harbor Freight. If you get the sale emails, and use the 10%, 15% & 20% off coupons that are available every now and then, you can get stuff really cheap. I bought this mill last year:
It may be a "cheap" import...but it does me just fine. The store price was $999. I printed out the internet price of $899, and took it in the store. They had no problem honoring it, along with a "20% off any single purchase coupon". It ended up being $720 + tax. That is literally half what another local place wanted for the exact same mill painted a different color with thier sticker on it.
My latest purchase was a 10" disc/48in belt sander combo. Store price was $209, but after all my coupons I got it for $143+ tax.
I don't buy all of thier tools...some of them are pure junk. I would never buy something like a planer or jointer from them.
