A starter kit is a crap shoot IMO but... Here are a few with decent quality
.2.3.5mm Pro Airbrush 7cc Cup W/ TC-848 Quad-Head Compressor
MASTER AIRBRUSH KIT G22,G25,E91,TC20,CRE COLORS
I started with the one from US art supply and still use the compressor and the guns are all for primer and some overcoat colrs. Best thing is to get a really good gun. Some of the lower end guns will just frustrate you beyond belief.
In retrospect, I wish I had started with this system HP-CS .35mm Eclipse Airbrush TC20T Comp 12 Colors All Acces but I had a limited budget. I did finally get a good badger 360 and an Iwata Kustom and although they are overkill, they can do anything I want as well as many things waaay beyond my skill level.
