Bundle of Holding currently has a Cepheus Engine bundle.

Since it's 2d6 base the settings, vehicles and adventures should be CT compatible.
For 9$ you get the Core rules, a Vehicle Design Guide, a Bounty Hunter's handbook and "Scout Base 947" which is a sort of home base for your crew, detailing the subsector system and world where it's located, and three adventure set there. This IMHO is the best deal.
for $21 you also get 10 different ships, "Class E starports" which is another frontier setting with only 4 inhabited worlds. This tier two bundle doesn't really do it for me, but maybe it'll be your thing.
