Whats next after MSTY?

Building my portfolio 100 shares at a time and will pull the trigger to get to 100 shares of MSTY in Feb. I'm wondering where the next play should be. Have about $1k/mo to throw at this, looking for the highest DIV yields as I am looking to get to house money quickly (i.e. recap initial investment).

Or is the answer what it always is...more MSTY?
