Sorry to hear about your ordeal, Mark. I've been there... more than once. One of my first boomers, one that was shipped from Korea by a US serviceman, was simply laid in a pile of shredded paper inside the box. Needless to say, when I lifted it out of the box upon its arrival, it basically crumbled in my hands.
Catherine sounds like she genuinely wants to make things right, and I hope she does. The simple truth is, many non-collectors simply don't understand how fragile these units are, how rough shipping is, or how to pack delicate items (I guess, to the uninitiated, boomers appear too heavy and solid to be fragile).
Fortunately, eBay's buyer protection plan works, and photos like yours would be pretty convincing evidence of poor packing. Unlike my experience with the Korean boomer, you have a pretty ironclad eBay policy to back you up if Catherine doesn't.
Good luck!
