Looking for a tablet? Check out this video before you go out there to buy one: https://www.youtube.com/watch?v=VH1WEYF8rlA
In my opinion, you do not need an expensive tablet. All the experiments I did in Krita before June 2019 was done entirely with a [Wacom Intuos Draw] I got for less than $100 when it was on sale.
Recently I went and bought [Wacom Intuos Pro Pen 2] to see if there’s any difference. I can tell you that there’s [not much] difference. If you’re new and or just starting out doing things digitally, get the low end ones. If you find that you enjoy doing digital art, then just upgrade to the screen tablet later on (the kind where the tablet display everything and you draw directly on it).
