Just thinking about what class to play next. Curious to know what people think the best story is they've played?

Thanks Vanor, you answered my question

On the republic fleet, there are those vendor's that sell to certain races I assume. When I click on them it has symbols for money I've never seen in my 30 lvl's of playing the game. How do I earn that kind of credits, or money, cause I like what they have for sale?
