/ic/ - Artwork/Critique

I bought a cheap tablet for $12 off of craigslist to see if I'd like digital art or not. after 2 weeks of using it I find it very fun to doodle in.
I mostly plan to make to make simple drawings like this (its the hunter from bloodborne), something you would find on early newgrounds.
the tablet doesn't have pressure sensitivity though since its old and cheap.
I'm going to get some extra cash next month and I'm wondering if I should buy a better tablet (something below $120)? do I really need pressure sensitivity if I don't plan on making serious or detailed art or will my cheap $12 tablet suffice? If I should upgrade then can somebody recommend me a tablet?
