[Michlib-l] PA system

I'm considering installing a PA system, and would like to hear from some libraries that have one. I'm not entirely sure one is worthwhile for us, so I'm interested in hearing thoughts on how useful it is, how easy to use. If you got one in recent memory, I'd also love to hear how you got it, how set up went, and if you're willing to share, a ballpark of the cost. Thanks to anyone who shares!
