I am a performance volleyball coach who is used to coaching with good quality and expensive equipment, but with volleyball, once you buy the equipment there are no other expenses.
Sometimes there is a need for a light volleyball net for school delivery of the sport and which is transportable. This net system is IDEAL for that and perfect for grass and beach playing. This can be used for delivering volleyball indoors and I have found a way to do so using badminton posts (which every school has, even most primaries) and using zip fasteners that I buy in packs of 100 from Amazon for £4.99. These fasteners secure the volleyball metal posts against the metal badminton posts net and voila, children play volleyball using badminton size courts. Of course the net can also be used to play in parks.
Cheap, yet good quality and can be used everywhere
Have not found one yet
