Kobalt=30 gallon tank•155 PSI max pressure, 6.2 SCFM at 40 PSI... These sell for around 475. You can shop and get cheaper. What ever you get I would get a piston type compressor just for the lower noise.
might want to add a water separator/ 5 micron filter to add life to your tools.
Say, how's it hanging? Yeah, you like the way I shined those up, yeah? They look nice. Maybe I'll buy a cheapshit compressor over at china boat is sinking finally. Yeah, you figure I could polish these out in a day, whereas I was reading over at the website about a guy spent 300 bucks on a 175 buck save. He was polishing about a quarter of the wheel in about 3 hours. Thing was, it kept on running and stopping just to get the kid's tires pumped up. Geee, so watt happened next? Well, after the 300th time his ears rang from that non-piston type pump, he started to smell smoke. WATT kind was that? You know when them chine knees units go out @ 300 buck a pop? No. Well, you see that bellow of smoke coming out of that motor? Yeah, that smoke. I now have to add 300 more dollars it's going to take to buy American, wear out I should have spent the extra 175, but now you see the cha-ching you go cheaping out in the cheap seats?
The math:
One time junk pile in hours spent on the cheap ~300 + 300 + 175 = $775.00
One time buy is out live your lifetime is buy American = $475 or less you shop around.
Make sense to you?
