Behringer EPA40

Small and portable battery powered speaker and mic combo

The Europort. Great little alternative to a megaphone - same concept, different design. This is the over-the-shoulder version (or you can rest it on a desk if that's your thing). Perfect for tourguide, classroom or meeting applications. Includes a corded microphone, and a big bonus is the minijack input for easy iPod connection.
