Instead of blowing money for a chance to lose, I decided to get my KDF science officer a Varanus. I was amazed how sweet this ship is. The repair drones are a real asset to STFs, it turns well, and takes a beating. Quite a bit more useful than D'Kyr's shuttle combat/heal accessory. Of course the Nebula is tough and useful... they all have their place, but the Varunus might be my favorite.
It's great to pay money, and get a ship! I hope Cryptic will let us continue to get new ships this way, because I don't have the luck to do it by gambling.
