Scored mine from Amazon, and although the shipment was delayed a few days, and the box looked a little worse for wear, there was absolutely no damage. I was concerned that they packed the two stones face to face with nothing between them, and only wrapped in one layer of bubble wrap and cardboard, but they were fine. Mine has the 10psig regulator, so I guess I got lucky. The only issue is the motor bracket is slightly off-center from the shaft, so I am unable to slide the motor & mandrel onto the shaft. I was able to work around it by installing the motor and mandrel first, then tapping the platter/shaft assembly onto it.
It's not "really" here until Santa delivers it on Christmas, so all I can do for now is tweak it, and dream of how good the pizza is going to be.
