devilbiss has a finishline kit. this kit comes w/ a clear gun, basecoat/primer gun and a touchup gun. can't remember the price, but it's a good starter gun set.
i have a devilbiss gti for clearing and a devilbiss plus for basecoats. i have a sata for priming and a iwata lph 100 for touch ups. i also have two airbrushes. an iwata hp-c w/ a .35 tip and a paashee w/ a .5 tip. i couldn't do w/o any of these guns. they all serve a purpose.
