I can give you a ballpark price of the pneumatic vacuum elevator. A basic 2 stop runs between 20-22k, and a basic 3 stop runs between 28-30k. Keep in mind different states have different costs associated with them, and therefore, the price may be higher.
I hope this helps

Keep a flashlight in it, just in case.Rupp said:What happens when your on the way up and the power fails?
