i just looked on ebay and that PH tester is $127 at the very least on ebay. Maybe you looked up the wrong one cause there are many levels of testers from Hannah. You might have looked up the 98103 which is the $30 tester. The HI 98130 is the correct one. Heres a link of the one i'm talking about just in case you looked it up wrong.
