Noone knows better than me that the light freighter is awful. The argosy does not carry enough cargo to make it worthwhile as a trading vessel (the light freighter does not either).
I want to know which plugs provide some good trader ships. I consider a good freighter to be something with 200+ cargo, tolerable maneuvering, and with enough shields/armor to prevent death while entering hyperspace. The plug containing the ship should also provide decent trading routes so the ship is useful.
Some good freighter ships I have seen:
Several plugs make the bulk freighter available (500 cargo, 150 space). After upgrades, it makes a tolerable trading ship, but there are many better.
Jumbostar from Clavius and Beyond (220 cargo, 3 turrets, overpriced)
Secure Transport from Pale (I forgot the stats, basically a corvette w/ ~200 cargo, and fewer guns)
Ore Hauler from Pale (5000 cargo, excellent armor)
The Trugati Trooper from {forgot, i think Galactic Scourge} (40 cargo, but cost only $30,000, great ship after the shuttle)
My current favorite:
AX-5000 from Galactic scourge (5000 cargo, well armed and shielded, but cost $25 mil) It mounts fighter bays (hawks i think), 3 or 4 turrets, ESG system (plug specific weapon), and shields+armor on a par with the kestrel. This ship was Fort Knox in space.
Quantumire had several ships with 10000 cargo space, but that plug has some other serious problems (not least of which is the lack of trading opportunities).
What have you got?
