I just noticed that Blinq.com has the Grundig S450DLX on sale for $34.19 shipped. These units are described as used/open box and may show minor wear and/or come repackaged. I believe you can buy from Blinq with confidence; I once had to return a product and found that Blinq made the process hassle-free.
You can purchase directly from Blinq or via Amazon.com (click on “Other Sellers” new and used).
