Wall mounted tablets...model / make suggestions

I’ve got a number of wall mounted tablets, all are hudl 2’s as the price and spec takes some beating and the HD screen makes a lovely looking control panel.

As is the way of things one of them has died and needs replacing, they are not easy to find so wanted to see what everyone else is using. Looking for nice screen with a sensible price.

All of mine our refurbished units from amazon… most are Acers, mix of 7 and 8 inch models. I try to stick around 70 to 90 dollars, and look for the best specs I can find,.
