Just a side note. I've used many Panelmate 1700's, over 100 through the years. The ones we used were the 6-8 inch screen range. Excellent graphics - wonderful display. Software is easy to use and bulletproof. Unfortunately these touchscreens all suffer premature failure of the backlight. It's a flat rate to repair one, over $1000. A repaired unit usually fails again within two years, sometimes much sooner. Hot locations make this problem worse - ambient temps of 95 degrees F, 35 degrees C, which is not that hot.
