NuVo touchscreens save $700 over Elan – Eddy has a total of eight 7-inch touchpanels — five NuVo P30s and two Elan TP7s. The $375 NuVo P30 Android tablets (pictured) mimic almost entirely the $1,050 Elan TP7 touchscreens. Buchan installed the pricier Elan panels where Eddy wanted on-the-fly configuration options and access to features like an alarm clock and motion sensor.
