I'm so happy my goodness this is amazing. So I finally managed to buy my tablet back in December and it arrived yesterday in the mail~
I got a Huion Pen Display tablet (model 190). It's the 19'' so it's 18.5'' across and I absolutely love it so far. For a cheaper Cintiq alternative as a monitor tablet, it's doing wonders so far. I still need to adjust the colours on my laptop to match the tablet, but they aren't too different in the meantime other then vibrancy.
