Well, I have never had the opportunity to use one, in 3D it is also easier to work using a tablet, I think more for the sculpture part.
I should try to save up to buy one.

We are waiting for you to get a pen tablet and fully open your talents!

Any brand or model that you can recommend that is not very expensive?

I'm sorry, I'm not very familiar with pen tablets either.
I'm using WACOM's.
It's a reliable brand, so you can choose any model.
The ones made in China are cheap, but I'm a little worried about the quality.
Choose according to your financial position.
