No idea about sites like that.

The only tablets I have seen in that price range outside of sales are the smallest XP-Pen ones. There is this 11 inch Veikk on Amazon that goes for 149.99 https://www.amazon.com/VEIKK-Full-Laminated-Graphics-Function-Shortcut/dp/B08G8CKSWK/ But I have never used one or talked to anybody that has.
