Been looking for quite awhile and finally decided to make my own hammock
http://www.hammockforums.net/forum/showthread.php?t=670 Thanks to Headchange4u and all the others!!!! Found an excellent source for zippers and netting. Goldenwest Swap Meet. Corner of Edinger and Goldenwest. Found zippers (size 3 and 5 in both coil and tooth) for $1.00 per yard and netting for the same price. The zipper they had was probably 50' so you won't have a problem with finding a long enough one, also gove me two pulls! Sorry do not know what the actual type of netting is but it's very slightly larger than no seeum. Extremely tough! stretches to about 50% (from 12" to 18") and very difficult to tear. Bought black myself but they had white, blue etc.
Thanks to all for the outstanding information! thought i would pass this along for any near by.
