Looking to sell some of my Canon lenses. What the best way to recoop most of my investment with the least amount of pain.

I want to sell my Canon 70-200 mm 2.8 (ver. 1). I loved the lens, but I only really use it a handful of times a year. Most of the time it is just sitting in my closet.

Should I try to sell it back to Amazon or use Ebay? I would rather deal with an organization than an individual.

 

Your thoughts??
