zephyr
For Christmas 2009, CCP gave every paying customer a Zephyr. A small ship equipped with a built-in probe launcher and immunity to attack from Sleepers. Which makes this ship perfect for scouting wormholes.
Unfortunately, this ship will probably never leave my hangar. Some asshat out there would destroy it just for fun as soon as I undocked. Instead, I'll hold onto it until they become valuable, and then sell it for a hefty profit.
