@Spankdawg - I never heard back from 5-11under, so I presumed he was out of stock. I did manage to get a couple of screens from here: https://voiceofthemummy.com/1979-82-microvision/
I'd recommend reaching out to the owner of the site first to see if he still has any, and be forewarned that his site lists them at $45.99 each but when you click the order button the cost is $99.99... which is what I paid. It was a bit pricey, but it's not like there are other options if you're looking to preserve your Microvision.
Good Luck!
