ACS NCP Plus is the latest ECP device produced by ACS up to 2012. After 2012, ACS did not make any new NCP units while they offered multiple refurbishement unit options. NCP+ units feature a similar interface as the NCP 2 models with reports generated in PDF format. They are among the quitest in the industry and can still be purchased refurbished from the manufacturer at the price of $40000-50000. Purchasing a used NCP+ at half that price together with a $5000-$7000 service / warranty plan offers a much better ROI.
