I took the advice on here recently to try the higher screen brightness Nexus 7 Gen 2 off eBay- so far, so good. I could see it on a kneeboard in a cub with or without a Stratux. Solid $40. Brighter than my 2019 Tab A SM-T290 or 2013 Tab S2 7 inch.
Strikes my like a iPad mini 4th Gen. I'm spoiled at work with an Ipad Air Pro Gen something new 10 plus inch.
In a Cub even a used phablet might do well, no sim/cell needed, and brighter yet S9 Plus or similar with a good battery life remaining. Swappa is a popular site, too.
If you dont have ADSB-In, you can get a cheap sim card plan and get metars texted to you.
