I just have to tell the group again. That last year I got a glass touch screen for my little girl and it works great. I looked at the ones that use the plastic over lays but could not see buying one ever 3 years. I thought I would let you guys know about the address and number again if anyone is looking for a touch screen for their child. 1-800-795-5140 and ask for Steve Brothers. The 15 inch is only $549.99 and the 17 inch is 799.00 And tell him you are the parent of a disabled child as they usually do not sell to people but he said he would if we mentioned our need. Kristina
