TDS210/220 etc. Display plastic cover?

[JMcC]

I'm looking to buy some clear plastic/polycarbonate to replace the plastic display shield on these scopes. I have 2 which are a bit messed up, one badly scratched & the other looks like someone made a habit of poking the centre of the screen with something. Displays themselves are fine. The existing cover is mounted (glued) to a 3-4mm foam 'bezel' which is itself glued to the LCD display. The plastic thickness is about .25mm or so. I've so far not found anything suitable I can use to replace the shield plastic thats not 1mm thick. Don't want to use anything too flimsy, but 1mm is a bit much...

Anyone have any pointers? I'm based in Europe.

Thanks,

J
