That kit you installed has gone up a bit ($283) but still comparable or even cheaper than the alternatives.   I might just go with Rapid air .   Of course, I hate missing the opportunity to do things the long, hard, expensive way - my usual mode of operation - but I’ll get over it 😆

Nothing worse than seeing water droplets coming out with your paint (been there done that).  One benefit I thought copper would have would be  to condense water quickly and earlier in the run; therefore water vapor would be less of an issue at the tool end(assuming I slant the lines to run back towards the compressor) and my tool-end water filters wouldn't fill up so fast.

That's how I feed the system in the shop, compressor is outside in an insulated shed with a small heater and a flex line goes up to the 3/4 pipe nipple I ran through the wall.

I did cheat a bit though, the remote tanks are ex FD air bottles from an old cascade system, rated for 2200 psi so my puny 150 psi air system doesn't make them sweat..
