Lot of good info here for you, plenty to ""sift" through. Only thing I'd like to add is that a cheap gun is... well... cheap. Made up of cheap materials and put together as cheaply as possible. They do, for the most part, work. Just don't really expect any longevity with heavy use. Some will agree, others will disagree. Just like all of this stuff, no matter the method, you can make it whatever you want it to be. As simple or as complicated as you'd like. Personally, my opinion, use the best equipment you can afford. Totally sucks when you're out at it and you have equipment failure.
Enjoy your time out there going at it!
