Spray gun advice

Certainly the devilbiss is the best gun, hands down over the other 2.

I might suggest that you consider hvlp, I have air guns, like these, binks and devilbiss. But I started buying the conversion hvlp.. Not as good as real hvlp, but better than siphon type high pressure guns.

With an hvlp it's small, you can take it with you, versus a compressor and gun, you have a turbine (small vacuum cleaner) and a gun.

It will spray all sorts of finishes. And without spraying the rest of the room...

Like Jeff says, it's hard to beat an HVLP system for a woodworker.

Large price range, and the more you pay the better overall results you will get with more types of finishes.

This one is highly rated for and by woodworkers. Has a number of hands on reviews on YouTube, check them out.

I have the predecessor to the above and use it for spraying everything from primer and shellac, to many paints.

I've owned three different HVLP units, in three prices ranges from $49 to the above, and would have been far ahead in results and reliability had I just spent the bucks for the above to begin with. Keep in mind this is a medium priced HVLP setup, you can spend much more.
