Many times I talk with people and they mention they draw too and just bought a super expensive tablet with super software etc etc. to be 'a professional artist'.
I always tell them: Take a paper and pencil, draw something. If it doesn't look good, you need to practice more, and buying expensive stuff is just a waste of money.
There's a lot you can do with just a €6,- bottle of ink and a €2,- 'student' brush. If it doesn't work, just practice a bit more.
