I wandered over to the Astak site and found this:

Is that the model you are looking for? By the way, the discounted cost is US$249. The only way to see that is to create an account and add the item to your cart. It's interesting this model only comes in black and white and only has 4 gray scale levels. I thought the new 6" model was supposed to be really great?
