Like Stick posted, Rolair is well made.
What you might do is call or visit a few of the air compressor repair/service shops and ask what they would recommend or what to avoid.
For years a cast iron oil bath pump was the gold standard. Those units seem to last the longest and the oil-less pumps seem to wear out quicker and from what I have been told, some are not worth repairing.
I have a Grainger USA made pump motor and a cast iron oil bath pump 25 gal. tank unit in the shop --a real work horse when needed. Only use it for nail guns, blowing out saw dust from tools, etc., it is probably a bit too much, but 'ya nevva' know when you'll need something bigger that will put out the air. I found this out when I need to use a cut off tool to remove some rusted on nuts and bolts. I do not spray with it as I have an old HVLP unit to spray water based materials.
Only problem I had in 20+ years was a new cut off valve. I added an extension to the tank drain for easier draining. I would recommend draining the tank after each use -- cheap insurance to insure tank longevity to prevent pin hole air leaks in the tank. Supposedly, the Teflon lined tanks will not rust out. Also run good filter(s) to prevent condensation from entering your tools or contaminating your finishes.
