When I bought my carrier I also bought two cutters, a 792t fuel tender and a 512t trit miner, I consider them an essential part of the carrier.
One of the best things about having your own carrier is that it can bypass engineering ships because jump range becomes much less important and refuel/repair/rearm are always nearby. Neither my tender or miner are engineered & don't need to be.
And for a new player now, making enough money to afford a carrier, fuel & upkeep can be done without engineering too, just from mining & salad hunting with an armetis suit in odyssey.
