I have this storm shadow still sealed on the box.

What is the best way to go about selling this, is ebay the best place? Should I get it graded first?

What do you think I would probably get as a grade for this figure? You can see that some of the thin weapons fell down a little, will this kill the value? I believe I've seen this happen before because the plastic isn't glued there and the thin weapons will slide under the plastic.
