I was into this for about $200 including the air regulators. I had the hose reels and hoses laying around so add for that.
The hose reels aren’t the self retracting baller ass ones (I is broke niqqa) they are the ones with handles. Decided it was probably a better idea not to mount em to the cieling 
But seriously, I was going to go with the ones you are talking about but this ended up being a last minute, spur of the moment, I’m pissed cause a snowcone just came out of my airline style project.
