This has been a reliable self-contained performance rig for a couple years. Works great with both battery and AC power. Purchased new from Sweetwater. No damage and only slight wear from gentle use. Includes the carry-it-all backpack(optional), original cable for the breakaway mixer, the bracket for mounting the mixer to your stand and the (optional) footswitch and cable. It's done well in a number of configurations and I have even used it with an external mixer for large ensembles. I'm trying to price it to move but shipping is super-expensive so there will be a discount for local pick up.
