What is the best football to use for playing on concrete?

I go to a school where there is no football, but during lunch we like to play outside in the parking lot. The thing is that we need to buy a ball every 2-3 weeks because the ball keeps slamming into the concrete and just basically taring up over time and then the air inside the ball pops out the football so now it looks like the football has a lump and its just not usable anymore, we've used up like 5 footballs this year, so whats a good football that will last a lot longer than the 20 dollar Wilson composite football's I buy at Walmart? Do I have to get an official football? The ones that cost like 70-80 bucks? Please help me!! thanks! :)
