Hardware for reading comics

How do any of you read your comics? I'm looking for something like a tablet/e-reader that would support either web browsing or adding files without using a proprietary store and color screen. Bonus points if the screen is huge and I can compromise having one that is old, a little slow/low refresh rate and low res.

Currently using a MS Surface which is great but really heavy and slightly clunky. It's also shared so I have to give it back occasionally.

First time poster, happy to see so many people on Lemmy.

Edit: formatting. Sorry, removed duplicate posts
