Paint guns .. in more better

[XLexusTech]

Hi I am in the market for a pint gun/Gun's. planning on doing my first DIY paint job, base coat clear + will be expoxying the floors and some sound deadining.

I was lokking at the devilbliss starting linke kit that comes with 2 guns one for base and primers (believe it had a 1.5 or 1.8 tip) and another for gun for clear.

Then I noticed thier are slightly more expensive guns that can use multiple tips and be used for base and clear and handle tips form 1.2 to 2.2/....

So i started to wonder which way to go... a few cheap guns or an multi use gun for a bit more $$$...

thoughts appreciated.
