I have a Vortech MP10ES (October 21st, 2012) and a Vortech Battery Backup, up for grabs in Charlotte, NC. Asking price is $280 for both ($200 for pump, $100 for battery if being separated). Everything still works like a charm! Pump doesnt go above 25% due to it being in a Nuvo 16 gallon.
If you have any questions, feel free to ask. Pump will be cleaned prior to pickup.
