I agree with prior posters that either the Vulture or a Courier,
my personal preference after weeks with both ships is the Courier, why?
Well mostly because it is fun to fly. fast and "can" outmaneuver a Vulture and outrun almost anything but a lightweight fit Cobra
My build for my ship is as follows:
http://www.edshipyard.com/#/L=707,4yH4yHmpT0__0__,2-6Q4s4s2C4s3m3c,4zM05U7O27dg7dg9pC
This ship is rather special in that it "really" benefits from a "lightweight" build my 4PIPS speed is 306kph and 416 boost and kicks it's maneuvering and lateral thrusting past an "A" spec Vulture (if i shaved off 5 more tons it would be 310/420) *for reference my 210 ton "lightweight" no weapons trading cobra maxed out at 320/450 empty
But does not suffer much as it is fully res/bounty/conflict usable, the dual beams pack a nasty punch and with (sys/wep) 3/3 can fire dual beams for 6 sec and single for 20 or (2/4) can fire for 10/40 respectively.
All that mind you with enhanced maneuvering *even at 0 pips it maxes at 240kph in combat and battle speeds are around 170* (only a a spec eagle/viper can go nose on to me close range in a vert-thrust pitch) and you still have 380+mj shields, a small target & 2A class scb's that can fully refill it from 1 ring.
Obviously i'm bias as i am in love with the ship, but it is worth noting that it can perform really well in the right configuration, and i hope this post helps in your future decisions.
