I'd love to try Flyball...

I love watching Flyball on TV but I can't yet drive and there doesn't seem to be anywhere near here where I can have a go even if I could get a lift. Is this something you can learn at home? Does anyone do a remote training course?
It looks so much fun.
I've got a collie that already loves catching balls, sounds like a perfect thing for us to try, but without a club locally we're a bit stuck.
Where can you buy a box that throws the balls in the air?
