For a cheap, Very functional drawing tablet, I recommend the xp-pen deco series. Any one of them are very affordable options (around a $100). I own one and love it, its cheap enough to not sink too much money in to, and functional enough to really let you see the potential of graphics tablets.
XP-Pen Artist 15.6 Pro for pc or Mac computer if you want something that feels familiar to pencil and paper. I use a XP-Pen Artist 15.6 Pro Drawing Tablet With Screen . It's amazing, you can get this from their official store .
