I'm selling my Atomic Z1 with a Sherwood Standard Octopus and BC inflator hose on Ebay. Opening bid $175, no reserve. I replaced all the plastic parts of the Z1 so it looks like new, and the Sherwood was barely used. I had the Z1 regularly serviced, as well as the Sherwood, but the Sherwood has been sitting around a while.
