i use a cheap harbor freight hvlp gun, as long as you keep it clean it will last for quite a while. usually a hvlp (high volume low pressure) gun requires about 30 psi MAX to work and spray a nice even pattern, I've used $900 De-vilbiss paint gun and my harbor freight gun and both take about 25-30 psi to work, just make sure your compressor can keep up with a constant use of air at that rate.
