This is posted on SlickDeals every once in a while. I find it very helpful, and also a decent indicator on how much I can sell them for on Craigslist once I get my shipment (hopefully this week). Ideally, I'm looking to make about $75 for each one I sell, which would pay for the two 32gb I plan on keeping. If I can also cover the cost of the touchstone charger and two cases, it will be an added bonus.
