When i was looking i seem to remember maybe 400 a pair went with the ezflex for about half that no air bags to worry about. Did the install myself including wet bolt kit over the course of two eveings alone with no problems. But being a saw mill equipment mechanic by trade i have the tools and equipment to do the job. Maybe you dont and have to hire the work out. I dont know, but like i said, maybe 4 hours total labor, so thats 400 dollars labor plus your 700 parts and that is still only 1100 dollars total even at a dealerships inflated prices. Call lippert and see what they would charge you for parts included a wet bolt kit before you jump on it. While your at it price out the ezflex parts and then decide for yourself if air bags are really worth the additional cost.
