What size do you need? There is 12mm and 1/2". I bought the last 1/2" one that Waterline Systems had in stock earlier this winter only to find that I needed a 12mm one. I can sell you the 1/2" one if that is the one you need - $70 shipped.
For the 12mm one, i bought a 13" SS rod on Ebay and made my own.
