I've heard a few friends using the Fender Passport portable PA which is small & easy for one feller to pack & carry. The speakers & mixer attach for packing into one item to heave around. You can get tripod stands for the speakers. They make more than one model. Sound seems decent enough.
I have what I call my "chick pa."   It's actually a Roller Rogue. It's a speaker with the mixer built in, & has wheels & a telescopic handle for a foo-foo gal like me to be able to easily roll it. I have two of them for when I need more mics plugged in. For small venues only.
