Paint gun for hobbiest?

Think about getting a gun that has different tip/nozzle sizes or one where you can buy different sizes that don't cost an arm and a leg.
Check out the Tech service sheets for the brand of primers/topcoats you will use for tip sizes like said. Tip size!! That is a big part of the pie!!! Like the key is quality of body work,,, the key is also in the small details of laying down the primer/paint, more so than the GUN!! IMHO
