Cheapest painting tools/setup

[Craftsman10mm]

Right now I'm looking to set up a makeshift spray room in my barn for a few projects. There are plenty of little things I want to paint, but one of the main things is the car restoration I'm working on. I already have some hvlp spray guns from Husky, but my questions are:

1. Cheapest compressor I don't need anything huge for what I'm doing, and I have no problem painting the truck in stages (i.e. the hood first, then the fenders, then doors, etc.). But having a tiny compressor run all the time would get annoying pretty quickly. What is the cheapest compressor I could get away with, and what size tank should it have? I'm thinking a 20 gal will probably cut it
2. Safety I'm still pretty healthy, and I don't want to destroy my lungs and/or brain. For a regular single stage enamel automotive/tractor paint with enamel hardener, what respirator is necessary? Reading the can, it says the product contains ketones, aromatic hydrocarbons, xylene and some other stuff. The ventilation will be decent, but I don't want a stiff breeze to mess up my painting. So, what will I need to protect myself? I think that just a regular paper mask might be enough for just an enamel paint, but I don't want to take any chances.

60 gallon compressor. Don't fiddle fart with a 20 gallon. Painted a dump truck once at a buddy's place with a 20 gallon, just the cab, it sucked monkey balls.

PPE, there's guys here that will say you need a full body condemn. If you're not doing this for a living, wear a shoot suit (they're cheap), gloves, safety glasses, and a good mask. That's actually overkill for a guy that's probably going to spray one car his whole life, but it's better safe than sorry.
