Skip that "On Duty Package", you will regret it. To put it into a paintball perspective that gun is like that marker rental some sap gets stuck with where every third balls rolls out the barrel. You will not be able to experiance airsoft properly with that gun. You can rent gun sometimes if you post in a game thread.
If money is a factor but you still need to own your own gun I would suggest a Crosman Stinger shotgun and a can of spray paint.
Just don't buy it when it is $119, it frequently drops in price to $89 or even lower. I picked one up lst month for $69.
