50 is too low imo. Especially seeing as we're getting them all consolidated in to one currency. Not asking for 1000 or anything like that, but even 100 wouldn't be so bad, imo.
Realy it doesn't matter 1st there is no weekly cap and I think the most expensive thing to buy is around 40 comms (the makeb stuff) and since you can keep them since you start getting them which can be as early as level 1, it gives you incentive to go out and use them. Note you can still buy that end game mod at level 10 on the fleet
