It is a Low D Shaw. They run about $80 US from Elderly. I have one and they are a bit of a chore to play. In addition the "stretch" it takes to properly cover the holes, it also takes a great volume of air to maintain the sound. But it is a beautiful sound.

I also love the "edgy" sound of the Susato, but must agree with alison (big surprise, being as how I relentlessly and shamelessly suck up to the fair one at every opportunity) with regard to the reliability at the upper octaves. If you are beginning, I would go with the Generation or Soodlum. Nice sound and reliable.
