Typing with the iPad keyboard

I've been typing with this keyboard for a while while taking notes and doing other things. I am debating getting a smart cover for a stand when I am typing for s better angle or getting a Logitech ultrathin keyboard. I am pretty good with the iPad keyboard. (I typed all of this on it). So I'm debating if I should just get a 40 dollar smart cover instead of getting that 100 dollar keyboard.
