If you take your time and pay attention to what you are doing then I suggest E-Bay. I bought a brand new pair of Zeiss binoculars yesterday for $375. The cheapest I could find a used set anywhere was $450. And the cheapest new price I could find was $549. Just do not get in a hurry, there are some unbelievable deals on E-Bay.
I have been shopping for about 2 weeks when I found them. Tom.
There are quite a few things that I would buy on eBay. High quality optics is not one of them.
