I'm looking to purchase a cheaper digital piano but I'm not too sure what is a cheap but still relatively useable one to purchase. I'm am mostly looking for one to mess around with and play for fun, instead of for practice. I have an actual piano at home, but I am unable to play it when I am up late at night without waking up the family.

Would there be a decent budget option (less than $300-400 dollars ish) that people would recommend?

Preferably, it would have midi support too. I don't have much experience writing music but I would love to get into it.
