Member of the Band

I’ve never mentioned this before but I'm in a band. A Worship Band. We're called Spectrum Band and we sing during our church's youth fellowship happening every two weeks. I'm an alto and have no other musical talent beside alto-ing. Being in a band has its perks, but that doesn't mean we're always united and stuff. Sometimes we have problems but most often, they fix themselves up quite nicely (Thank God!) Meanwhile, our equipment can do some upgrade. But everything’s simply so expensive on the web. What does one have to do to find cheap eminence speakers around here?
