I am looking to find some not-to-expensive equipment for playing music at a school. I am not sure how big the room is going to be, but I think 2 speakers would cover it. There is going to be a guitar, piano, and maybe drums. Basically I am looking for something that is portable and can easily be moved around. I guess I would need a mixer/monitor, a few mics, and thats all I can really think of. Thanks for the help.
