actually there is no such thing, don't worry about it, or about any such nonsense as PASA IKO etc.
These alphabet soups are not very nutritious!
They can't make you skilled or safe.
You don't need a packaged resort experience to learn, and there are shops in the SOBX and SC that can help you just as well as in OBX. OBX does offer great flat water and more reliable wind than elsewhere in the southeast though...
There are also lots of options in OBX. Do some research, ask around.... You don't have to just choose between the red barn and the pastel palace.
Do make sure you get someone with a focus on safety.
I can't really be more specific because I am not personally experienced with the instructors. I learned elsewhere, though I live in VA and ride also in SC and NC.
BTW "quiver" is just jargon for your collection of gear, like a golfer's collection of clubs...
For example you might take lessons, get a 12m kite, and ride around in 15 knot winds a while, then realize you also want a 9m kite so you can ride comfortably when it is gusty and up to 25 knots. Then you would be able to say, "dude I have a 2 kite quiver that is good from 13 to 25 knots. Or maybe 30, uhh 27?.."
Likewise you might get a surfboard after a while or whatever....
I just meant that if you go for a lesson at real, once you have some skills, they can help you hone them. They also have a lot of different gear you might demo, and by watching you ride, they might be able to help you get gear that suits you or complements what you already have. -surely they would be happy to sell you something anyway!
Which gear to get as you progress, a friend might also help you choose wisely. Hopefully you will make kiter friends and ride with them, trade gear around a bit to see what suits you...
Another thing, I hate to be a pimp but I have to say, the slingshot gear is more heavy duty than most other brands. Also, don't mistake any of what I say about Real as a diss, they run a great operation in a lot of ways.
BTW still disagree with edt, look at the gear.
Obviously if it is highly worn, don't buy.
You can get year-old top of the line setups for 40-50% of retail, with little wear.
What to look for is simple:
crisp, shiny fabric with out fading or frayed edges at seams.
Intact stitching without stretched out holes around the threads.
Lines and bridles that are smooth and not all fuzzy or totally dull.
Pulleys and cleats that operate smoothly.
No major corrosion (slight staining at welds is ok for SS parts).
Repairs should be few and small, or the price should be low.
Basically, common sense and inspection or good detailed pictures will show the condition of a kite pretty well -better than the condition of a boat or a house or a car!!!
