Since I play I bought the following ships :
1.)for fed char
-armitage -interesting ship and OP if you use advanced danubes
-fleet patrol escort -not impressed about it
2.)for kdf char
-corsair deck flight -for tachyon drones which were later nerfed and are useless now
-ch'tang bird of prey for jump console -fed can have the console with 800k on exchange .
I was ready to buy LTS just for the kdf destroyer but the ugly stunt made with tachyon drones made me very careful about what I will buy in future.
Now I would love to buy the full pack (5000 zen) for my kdf char which is a raptor flying captain but I CAN'T .I won't buy it for fed char because now it is the time for kdf to have a new ship.
So think about that :there are kdf players who would love to have the opportunity to buy it and they can't.
Honestly just do all the free zen offers you can and some surveys and I guarantee at least enough for a ship within a couple days. Even once all the good offers are gone, I still get one master key per day by doing a couple surveys.
Make sure you are going to earn zen page from American IP address cause the Canadian free offers are practically nill
