My two cents?

Don't.

Don't get a D'Kyr until they decide to go back and knock the rust off the pre-lockbox ships.

The D'Kyr it's self isn't a horrible ship, but the pet is ... awkward at best. That's pretty much it's selling point. Anything else it does another ship does better. I'd suggest a Long Range Science Vessel Retrofit over it (or the Atrox if you just like carriers).

Edit: Word of warning about the Atrox. It ages less gracefully.

I've seen a total of two D'Kyrs in my time (not counting my own), and never for longer then a a single match. If that's any hint.
