If you havent ordered yet the drinking valves are alot cheaper at http://www.bassequipment.com/edstrom.htm. Id suggest getting the tank connector at bass as well. The standoffs and valve clips are cheaper at Agselect. For the rest call up a local sprinkler store and buy 1/4 OD line, tees, elbows, and drains. (instead of the $60 at either online place it is closer to $10). This is for the 3/16 barbed system.

The one thing I wish I had done differently was to get clear tubing instead of black. These systems will get algae build up and its hard to tell in black tubing.
