Well, after a lot of scrounging for dil and doing surveys, I've past the 2000 zen mark and 2500 is within reach, so I figured I'd look at the C-store ships and figure out what to buy. Of course, the selection there is pretty huge, so I reckon I should ask for advice before putting my money down.
My main toon is currently a KDF Sci Captain, with a bunch of ships already: Mirror Vo'quv, Hegh'ta Heavy BoP, Scourge Retrofit, Kamarag Retrofit, and the Marauder Cruiser. My alts are Fed Engineering (in an odyssey), Fed Tactical (patrol escort), Fed Science (Nebula Retrofit) and a Romulan Tactical (Ha'Feh).
My taste in ships runs towards "cool" - I'd rather have a bag of neat tricks than something that just does overwhelming damage, provided that said tricks can finish the combat before it starts to drag and get boring.
