Anyway, I saw this one, which looked like it might meet my needs, and which, the seller says, can be shipped worldwide. With a few exceptions:
Shipping to: Worldwide
Excludes: Africa, Asia, Central America and Caribbean, Middle East, Southeast Asia, American Samoa, Australia, Cook Islands, Fiji, French Polynesia, Guam, Kiribati, Marshall Islands, Micronesia, Nauru, New Caledonia, Niue, Palau, Papua New Guinea, Solomon Islands, Tonga, Tuvalu, Vanuatu, Wallis and Futuna, Western Samoa, Bermuda, Greenland, Mexico, Saint Pierre and Miquelon, Albania, Andorra, Austria, Belarus, Bosnia and Herzegovina, Bulgaria, Croatia, Republic of, Cyprus, Czech Republic, Denmark, Estonia, Germany, Gibraltar, Greece, Guernsey, Hungary, Iceland, Italy, Jersey, Latvia, Liechtenstein, Lithuania, Luxembourg, Macedonia, Malta, Moldova, Monaco, Montenegro, Norway, Poland, Romania, San Marino, Serbia, Slovakia, Slovenia, Svalbard and Jan Mayen, Switzerland, Ukraine, Vatican City State, Argentina, Bolivia, Chile, Colombia, Ecuador, Falkland Islands (Islas Malvinas), French Guiana, Guyana, Paraguay, Peru, Suriname, Uruguay, VenezuelaThat's quite a list of exceptions, isn't it?
If you look at the dropdown menu that lists the few places to which they do ship, it appears that they define 'worldwide' as the US and Canada, parts of western Europe, Brazil, and New Zealand.
Ebay ought to police their sellers a bit and impose some standards of honesty. Lies of this sort will damage the credibility of the whole marketplace.
