Interesting name. In my opinion it is a very brandable name. I can see 'Auzoo' being something related to kids, animals, toys, cartoons, or a Web-2.0 site. I would park it for now and start promoting it. You never know when an end-user will come along. Also, don't lose hope if nobody shows interest for a long time. I've had many domains that I have parked and received random offers on months after I parked them.
Right now I'd imagine mid-$xx for this domain alone (i.e. undeveloped, etc.). It can only go up if you develop the name or receive offers.
Good luck,
VYFX
