Joe,
I've had a Sears 5hp, 20 gal vertical tank compressor for several years, it has worked well for everything I've ever used it for including using air tools that wouldn't work with the little 2hp 4gal Harbor Freight compressor that I had before it, the little compressor would run an air tool for just a minute or so before the tank was empty and it was running on just what the compressor supplied which wasn't enough, it just couldn't keep up with the demand. I use this one with cutoff tools, die grinders, air hammers and ½" drive impact guns, never has let me down.
They don't make that model any more that I can see, all of em are rated less, seems to me it's rated at 13 SCFM @ 90 PSI, I paid less than $300 for it.
The vertical tank is nice since it doesn't take up as much room in my shop, vertical space is more plentiful if you know what I mean. The only trouble I've had with it, is I knocked it over once and busted the supply tube off that the control mounts on, got a new control from Sears and replaced the pipe.
