 I bought an ARB about 6 years ago.  Had no trouble and pumps each tyre from 15 to 38 PSI in 90 seconds. No overheating after pumping all four tyres. I use it at least three times a month after beach fishing.

Its a little more expensive than the run of the mill models and if you plan on using it often its the way to go. If usage is rare and occasional then I suggest a less expensive unit from Super Cheap or similar will do the job.

Had cause to replace mine recently.  Bought a twin pot one from 4WD Supercentre. Works well and very fast. If you have a store near you get it there rather than online...cheaper.  Have only used it t re-inflate after a run on dirt so can't comment on its longevity. 

Had an ARB one (the one in a toolbox with a mini tank on it) yonks ago but it carked it so expensive doesn't mean fail proof.  Since I use don't use one extensively I figured a cheaper one would suffice.

I have three ARB, but it was mainly about fitting them in a space. 4 litre air tank, moisture trap, additional heat sinks & fan cooling. In the process of installing an after cooler.

Work out what duty cycle you are prepared to be patient with.

The graph is from ARB. I haven't been able to find worthwhile information from other manufacturers. ARB do provided reasonable figures as a starting point.

Manufacturers should be stating SCFM (standard cubic feet per minute), CFM is a meaningless statement as it is with zero pressure or in other words 1 atmosphere which is a bit useless!

Same as a "150" psi compressor, but at zero flow!

Ideally you want CFM at 90 psi at 21°C. Something meaningful.

 

Also as a rough guide, for every connector & every metre of air hose subtract 1% of the compressor's capacity. May as well factor in electrical cable length as well, as they always undersize cable.

If you want your compressor to work & avoid Murphy striking! Do not use it longer than its duty cycle, which will be for a 21°C day.

As a bit of a back of an envelope guess I would reduce a compressor's duty cycle by 2% for every degree above 21°C.
