i have 2 emglo compressors, one that has a single tire and is moved "wheelbarrow" style. i use this one for framing houses as it is capable of keeping up to 4 nail guns operating vigorously, it recovers in about 12 seconds and is very, very quiet for a 5 horse motor. it uses oil and has two 4 gallon cylinder tanks. the other model uses oil too and has 2 two gallon cylinder tanks stacked on top of one another, recovers in 9 seconds, and is moved using a handle which is welded to the frame, i use it for running smaller tools like pin guns, brad nailer, and trim staplers. i figured i'd buy the companion incase one of these went down, or just needed something around the house for tires and such. i caught it on sale at Sears for $123 or there abouts. i couldn't resist.
BTW, i use the iwata hp-cs as well, and its smooth trigger action and fine atomization of paint made the $40 overpricing melt away with the first session!!!LOL. i have several airbrushes, but the hp-cs is my workhorse, all around airbrush of choice. later.
