Fishing net buoys are made of a hard closed cell foam and cost about 50 cents a piece each, found at most tackle shops. Just enlarge the hole for the locline and paint it whatever color you want if you don't like the look of the tan buoy.
Here's a pic of my DIY rig showing the buoys. I have since painted them black.
