I've been doing some PFI trading after .85 came out, but I've stopped it a few months ago. Trading is simply too much of a chore, especially since the reward, a capship, isn't that great anyways. Sure, I'd love to have one for the [1st] but mainly for the RP and not the PvP aspect, but screw that - while RP is worth a lot to me, it's not worth days of RP-low grinding (when I instead could actually be enjoying a *game*).
I finance all my chars through bounty hunting. It gets me enough cash to keep my chars repaired, and to occasionally buy me a new VHF or, if I save for some time, a GB. It might not be as "lucrative" as trading (haha), but at least it's fun.
