Unbreakable cups !!

This may sound trivial but I want to keep my shiny new (to me) Oceanis 323 in as original condition as possible.
However during a casual gybe my crew, on pulling in the jib sheet, managed to dislodge TWO unbreakable cups from the holder infront of the wheel; the consequence being cracked unusable cups lying on the cockpit floor.
Anyone know how i can replace them ??
The nearest I got was an American site selling the complete dinner set for over $200.
