I can understand how this might seem strange.
You mention that a 1260 board ended at 350 EURO on ebay and you can buy a new one from Vesalia for 250 EURO. Here is my wild guess; the 1260 you saw on ebay was most likely a Blizzard 1260 produced by Phase5 and the 1260 at Vesalia is most likely an Apollo 1260.
The Blizzard boards are imho better build cards, and since almost everyone prefer a Blizzard board for their A1200 it's most likely a common thought about the Blizzard brand.
A Phase5 Blizzard 1260 is in fact better than a DCE Blizzard 1260, eventhough it should be identical cards. The Phase5 boards can be deactivated with a keypress, the DCE boards can't.
The Apollo boards a good boards as well, but I would at any point prefer a Blizzard board instead of an Apollo board, even though it would cost me a bit more, so the wild prices on eBay might not actually be so wild afterall, but more an indication of a well reputated company with quality products.
