Hi I got a Pinpoint pH Monitor for Christmas and have decided I want to "trade-up" to a pH controller....anyone interested in a practically new Pinpoint Monitor? Original box, instructions, pH 4 & 7 calibration fluids included. I'm asking $70 (includes shipping in the US). E-mail me off the list. Do I need to keep the probe wet during shipping? Thanks Tom Brennan Brennans at ix_netcom.com
