It would be helpful to know what you are going to use it for..... initial epoxy primer coats, high-build primer/surfacer, painting chassis/frame/suspension parts, or high quality finish coats in base/clear. You'll likely need several guns to do it all.
I know nothing about using a paint gun , I’ve only used rattle cans until now, this will be a new experience and learning curve for me.
A mini or touch-up gun is handy for small areas and painting in tight quarters. You can get a cheap one for under $25 and it would be fine for what you are doing. If you can get your desired color in a spray can, you can still go that route. A spray gun obviously requires more supporting equipment.... air compressors, filters, pressure regulators, hoses, respirator, shop ventilation, etc. Do you already have this stuff or are you starting from scrach?
I've painted everything under the sun with the Harbor freight paint guns... epoxy, lacquer, enamel, urethane, basecoat/clearcoat. Not bad guns. Just need to do some practicing with a gun to figure out paint mixtures, thinning, adjustments on the gun, and applying. Always best to start with something easy, like primer. That way, if you mess it all up, you can sand it down and keep trying until you get it right. Once you get that down, you can practice with the shiny stuff. Always make sure you read the tech sheets for the paint you are using (thinning/harder ratios, required set time before spraying, sanding grit required before applying, etc.). Start with small amounts mixed up for spraying (make sure you have small paint-mixing cup to get your paint ratios correct)... you don't want to make a bunch when you are first learning how. Otherwise you end up wasting a bunch of expensive paint. Also, buy a volatile paint mask so you don huff the stuff, some of which is bad for you. Dust respirators don't work for solvents. You can get a good respirator for painting for about $20.

You know if you spend $300 on a used sata on ebay. (RP) and if you sand the car correctly. Then paint the car with the fan almost open all the way. That $300. will be forgotten when you see the finish. Just sayin. I have yet to run a car with an Sata RP. clean car good. And tack car good with a blow gun. BAM!
