If you did buy it outside of the ebay system, who initiated that? If the seller did, and you have emails reflecting it, ebay will work with you, and probably ban the seller.
Agreed.
To other posters. The condition of the lens likely normal for a well used 17-55. That is not the issue. The problem is that the seller represented it as "looks and works like new" in his E-Bay posting. I've purchased stuff in less than stellar condition on e-bay. The difference is that the deficiencies were fully noted and described in the sale ad. That is not the case here.
