Cast iron, reasonable size, good size air filter, reputable name. You should be able to get parts for it forever.
You really have to ask yourself what you are going to do with the compressor.
Drills, drivers, nailers, wrenches really don't use that much air.
Sanding, grinding, sand blasting all hammer a compressor.
With a DA sander you will
feel fine if the pressure drops but as it does it will begin to leave swirls that will show their face when you go to finish. You need running pressure, pressure in the line before the tool with it sanding over time. You set the regulator by that pressure. We have an inline gauge we put in to test at each station.
You said you are running line. Beware long distances and small ID lines.
If you are running any distance you need a larger "main" There are pressure and volume drop over distance. If you can make your air lines run in a circle feeding off the circle it is the best solution. Finally the hose to the tool. Running a 100' 1/4" i.d. hose before a sander is a disaster, might work with a wrench but you will likely lose force and speed. You are better running a reasonable length 3/8 I.D. line and then terminating it with a 1/4" whip to keep the weight of the hose off the tool.
Finally a lot of the noise of a piston compressor comes from the air intake. If you can plumb it a short distance out of the room you are working in it quiets things down a bit.
I like air tools for serious work. For small projects which most are at home electric is fine.
I have a small compressor at home, I use electric tools mostly. If I have a big project I do it at work (lucky me). At work I have a 30 hp rotary screw. It puts out a legit 100 cfm all day every day, totally different situation but every tip I gave above applies no matter the size of the compressor.
Have fun.
