I bought my PRS-505 at a Blue Temple here in central NJ. They are on the
Best Buy website, but currently listed as Out of Stock. They had a tiny display in the store before Christmas, but I haven't seen it since. It was very small and would likely only found by those searching for it. I recently sent my broken PRS-505 back to Sony for replacement. They called and mentioned that their supply was very short, but they were expecting more soon. About a week later they emailed and said they had one an were shipping it out. You might have better luck at a Sony Store. There is one at the Menlo Park Mall - call first.
