Here is a quote from a fellow who writes for a magician's magazine. He suggests that a Happie Amp and a Honeytone mini-amp (belt pac for birthdays) will do what you need.
Christian Conjurer Magazine January/February - 2009 Vul.53-1: "Portable sound systems for Entertainers"
""After reviewing the Danelectro Honeytone N-10 Guitar Mini-Amplifier, Apollo Portable Wireless 25w PA system, Fender Passport 150 Portable PA system, Nady WA 120 Portable PA system with Wireless Omni-Lavaliere Mic, and the Happie Amp (referred to as GTDAudio system) "Final Recommendations and Tips For most performers, I would highly recommend getting an iPod, Honeytone mini-amp, and the GTDAudio system (that's the Happie Amp). That would allow you to get through most performing situations with a great audio system that can act as a backup for a built-in house sound system or as your primary audio." - Tim Cimbura" - Tim Cimbura
