Any tablet expert please help a newbie out.

1. Brand. Preferably mainstream brand for reliability.
2. Budget. RM700-1000. Looking for a budget one, but don't mind topup.
3. Specs. (Ram/Proc/Camera's MP/Screen size). Prefer bigger screen like 10 inch. Decent ram and unsure about camera MP.
4. What you need in the tablet. For reading, video learning, casual browsing, and maybe light gaming (stardew valley for my mother)
