ZhuZhu Pets - Funhouse Set with Hamster will be available at Amazon.Com on Sept 1, 2009 for only $29.99. You can pre-order now!
I'm planning to get one but for Pia but I have a bad experience with buying stuff online. I bought an adapter/charger for my ASUS EEEPC two months ago but the item was lost in transit according to the seller.
Anyway, I think I'll just have to wait until zhu zhu pets become available at the local stores.
