Yet another recommendation thread.

Hey r/keys! I enrolled myself in a high level music class with limited idea what I'm doing for next semester, so long story short, I need to teach myself some keyboard rather quickly. I'm looking for something cheap (as cheap as it gets), but it's gotta be able to connect to my headphones/laptop so I can be terrible silently in my room. Any recommendations (or links to tutorials) would be appreciated! Thanks!
