Someone on craigslist is selling a brand-new-still-sealed Apple TV for $160. They said the retail was $230, so it sounds like they think it's the 40GB model. However, I emailed and asked for the product number and the reply was MB189LL/A -- which is the 160GB model. Seller seems very eager to sell, willing to meet me today, travel to where I work, etc. However, by the tone of the post and the email responses, the seller seems very knowledgeable -- too knowledgeable IMO not to know the difference between the 40GB and 160GB models. What do people think?
