a couple months back i was doing this and was selling them on a differetn forum(repticzone) and sold 3. now i found this forum and thought i would try again. i ahve drippers that i make that are the same as wat were on the chamleonjournals.com. the only difference is that mine hold more or less. the one im using holds 3/4 gal. i can reduce the size and make them slightly larger or smaller as you would like it. the basic one is what im using and are $10 plus shipping.all drippers come with a brass needle valve and up to 3 feet of tubing. just send me a message or respond to this thread if you are interested. thanks all.
