devilbiss finishline is a great gun for starting. and its not a cheap gun that will fail on you as you progress. id recommend the 1.3 tip. its perfect for base/clear. and you can still get primer out of it if you need to, just not efficiently. but you can always buy a larger needle and air cap and swap out between the 2. and the compressor needs to supply 13cfm for this gun @23psi inlet.
