Looking for a portable PA+speaker system that I can use with a mic and keyboard live, and possibly a guitar at home.

My budget is anywhere between $300-500, and yes I am willing to go used. Location is Los Angeles.

This looked pretty decent to me, but I'm not sure how loud this guy can go.
Anyone have any experience with the fender passport series? Would I be able to play with drums and not get completely drowned out?
