A while back some one had some Extech Exstik pH100 meters for sale. Some had damaged electrodes, some were O.K. I bought one and it worked. He is selling off the rest of the lot on ebay as is, but cheap enough perhaps to make it worth replacing the electrodes. Here's the link:

Didn't know where else to pu this but I'd like to know if anyone has any experience with this PH meter. http://stores.cheeseconnection.net/ph-meter-hand-held-hanna-instruments-champ-ph-tester/ (http://stores.cheeseconnection.net/ph-meter-hand-held-hanna-instruments-champ-ph-tester/)
