I use an Intuos 5 nowadays, I used a very cheap no name brand when I started out, and that did its job well enough. Even tho it was really small. For a beginning artist, I would recommend nothing too expensive, but get something that’s not too small, because otherwise you’ll have to re-learn how to draw on a bigger space if you upgrade.
I heard monoprice tablets are pretty good and cheap. But make sure to research them, I heard they don’t like two monitor setups. I do like Wacom, their drivers are insane and there’s a small chance the driver will die every time you look angry at your tablet, other than that I’ve been very happy with my Intuos, it took a lot of abuse over the years and I like how it feels. I also heard good things about the Bamboo, Wacom’s beginners level tablets, too. So I would probably go with a Bamboo. But in the end if you don’t have too much income to spare for a tablet and you just want to draw, get whatever you can afford. Any tablet is better than no tablet. Any drawing is better than no drawing!
My advice for new artists: Draw. Keep drawing. Don’t stop drawing. Every day!
