Not sure of the 'legality' of asking this, but I've read the FAQs and I think I'm ok... Anyway, I have a 20D and upgraded to a 24-105mm F4L lens over Xmas, which really is fantastic to use. As such I'm not getting as much use out of my 70-200mm F4L lens as I used to when I had my 18-55mm kit lens, plus when I do use it I'm finding it a little short of 'reach'. So I'm going to buy a 100-400mm F4.5-5.6L lens and sell the 70-200mm. Now I no longer have access to the MM here, and given how I only ever like writing thoughtful posts (as opposed to the "me too" variety) it's going to take me forever to get to the 250 mark. So my question is what would you guys recommend as the best way for me to sell my lens? It's in immaculate condition, and has a Hoya SuperHMC Pro UV filter on it too, so I imagine someone somewhere wants it. Is eBay the best bet - have to admit I've never sold anything on there.
