Aeroponics! Nozzless....

I just recently bought two, 45 gallon buckets and 6 10in net cups and they look awesome, soon to be getting the water pump and PVC, i was wondering if anybody knew the best place to get cheap 360* spray nozzles?

Do you have more information? Pics of your setup, even if not finished would help. 360 degree nozzles for low pressure applications are really cheap and not really all that different. Air atomizing nozzles are more expensive. What kind of pump? How do the 10" net pots incorporate into the buckets?
