If you can find a Samsung Galaxy Tab s5e, they’re cheap and remarkably functional for the price and size. I’ve been using one for years for light use. Mainly streaming media and internet browsing. Accessories can be a bit limited due to the age of the device.

Otherwise, an older iPad will not disappoint.

Tablets have really matured recently. Not all changes have been good but the average price for an actually usable tablet has dropped across the board.
