starting off with what? paint guns?

I would have to say either SATA spray guns or Iwata.

Sata if your starting off bc they virtually spray perfect out of the box. Iwata if you know what your doing and know how to set up a gun.

Sata will get shit done dont get me wrong with a professional look
Iwatas are more for the painter that wants a BETTER look but knows what hes actually doing and knows what kind of finish he wants.
