For a good starter kit, the Paasche H Set is excellent. The Paasche H is an easy use, highly capable single action AB. Aside from the airbrush, you get 3 different size tips, a color cup, small and large siphon bottles, an extra small bottle, and a good quality braided hose.
As for the basic needs of a kit, regardless of airbrush type selected, see if the kit has a "complimentary" can of Propel. Since you'll really want to have a compressor with a regulator and moisture trap, any kits including a can of propel are charging you for something you really don't need.
Another thing to look for and avoid is a lightweight, thin, vinyl hose. My experience with the cheapie hose on my Badger 200 led me to quickly purchase a heavy duty braided hose, so if a kit has one, you're really paying for something you don't ultimately need. Ironically, the thin vinyl hose never annoyed me too much with my Aztek, presumable because the Aztek's hose coonection is at the end to the airbrush body, so the hose would be behind my hand and arm and out of the way.
Depending on the AB selected, does the kit come with a color cup? Although Badger's design for their color cup leaves a bit to be desired, I still find a color cup instead of a siphon bottle to be more convenient 90% of the time, so if the kit includes one, that is something that you won't need to buy separately.
Dixie Art does have really good prices, and in my one dealing with them, the order was promptly shipped. Like tho9900 says, free shipping for orders over $45.00, which can amount to a big discount in an of itself.
