I have two 580ex II speedlites up for sale. They are both used but I took excellent care of them. Both come with the original box and have the case, instructions and the table stands that came with the flashes.
I am looking for $350 per unit plush shipping costs (this is what they are selling for used on ebay) but I am willing to accept $650 plus shipping costs for the pair.
You can email me at firstname.lastname@example.org if you are interested.
I also have a 430ex for sale as well if you were interested in that as well.
