For info - I have the 50L dual motor version of the Hyundai you linked to.
It's fine for DIY stuff - it drives an impact fine (though I rarely use it now I have a Dewalt battery job), spray gun - though I have only used it for applying ACF50 to my bike not like I am spraying an entire car panel each time, more of a spray, wipe and move somewhere else - I have also ran my sandblast cabinet off it, but it runs out of puff with that and as for a Tornador, literally seconds of effective usage...but it does recharge quick and quiet. I use it most for blasting water around the doors and lights etc when drying the car or bikes and it is absolutely fine for that as it charges back up while you are moving around. Same for pads - you are literally using it for a few seconds at a time.
I had a 100L SIP professional series before it (2nd hand but I rebuilt it all) and that was far worse - it took so long to refill that the motor just simply could not keep up with high demand tools. Also bloody loud!

You have to spend considerable money before you get out the realm of weekend warrior/odd DIY job and also don't believe any of the hype claims - the vast majority of lower end compressors list their CFM as the calculated value from the piston displacement and is absolutely not close to the true free air delivery.
Taking my twin Hyundai as an example, they are quite open about it - headline grabbing value of 11.5CFM but reality is actually 5.8CFM at the end of the tool line.
