My opinion:

1) I'm opposed to stuff-for-money. That's just not how we roll.

2) I prefer that the most common way to play a non-standard character is through earning it through RP.

However,

3) I'm not completely opposed to the idea that an odd character here or there could be given away very rarely as some kind of contest award or the like. Maybe we have a contest for a month to see who can make the most improvements to our web site or do the most for marketing CF and the winner gets to play an arial paladin or elven assassin or something.
