I use an XP-Pen Deco 01 V2, a basic $60 USB drawing tablet with no screen that I find really reliable. I like the paper texture cover it comes with, and the pen doesn't need a battery, which are both pluses. After SLARPG released and I had the money to do so I bought an iPad to try and get into drawing directly on a screen, but honestly I'm so used to drawing on cheap non-screen tablets at this point that anything else feels unnatural to me. So now I just use the iPad to read comics lol
