Suggested tablets/writing pad for online teaching and giving maths lectures
XP-Pen is a good off-name cheap brand. However £50 for a device with a 6x8 screen seems unrealistic, especially after the pandemic drove demand up. If budget is your main concern, the first thing I would cut is the screen. Getting used to a tablet without a screen takes some time, a bit like touch-typing, but once you do it it's not that bad and you can get some good deals.
