Decent iPad that supports Apple Pencil + Procreate is a good combo, just keep in mind that if you're into sketching, you'll want to get yourself a decent drawing glove too. This one is by far the best one I've tried so far: Articka Drawing Glove for Digital Drawing Tablet, iPad (Smudge Guard, Two-Finger, Reduces Friction, Elastic Lycra, Good for Right and Left Hand)
