No ideas really...your own sound ok, like lower shipping etc but do you even know how ebay works?? Do you have a scale? I would buy at least a couple of things first and get a few FB that way, while learning a little bit. It generally isn't a good idea to just jump in without knowing what you're doing.
I won't buy from a zero FB seller (for reasons stated above), but even 1 or 2 gives me an idea of how they handled the transaction.
And one thing I can tell you for certain..NEVER ask for FB. Some people give it & some don't But asking for it is asking for trouble. You may end up with a color you don't like
Good luck
