Looking for some start-up equipment for your band? My Harbinger HA 60 PA system has served me well for jamming with friends. You can play with up to four instruments and microphones, adjust levels for each, and produce a very clean sound.

The system is portable and I still have all the packaging material.

Here is a link to some reviews: http://www.musiciansfriend.com/pro-audio/harbinger-ha60-pa-system

I bought it new for around $200 in 2013 but will part with it for only $140.
