Craigs list works too, but know what your looking for, and getting into price wise. I got my "Brand new" 6 pc
Yamaha Stage Custom Advantage kit last year from a guy that needed to unload it fast as he was shipping off to Iraq. He asked $700 for it with 3 crashes a ride and hats. Told me $600 cash takes it, but it had to go that day. Walked in the door and saw in amazement a brand new kit, stool, hardware, cymbals, etc for $600. Out the door I went with my new kit and a huge smile on both of our faces! Good luck!
