I am unsure about flyball equipment. But Agility equipment all varies. tunnels can cost anywhere from 50-150, same with chutes. and weaves about 40-100. I dont really know about the other equipment for buying... I made my tire, jumps, teeter, walk, & a-frame(and painted ) I quess it wasnt to hard, but it is worth it because I use all of it almost everyday during summer!
Hope that might help--- You could also go on different websites and compare prices
