Legacy Lenses - Buyer Beware!

I find that it's often the people with thousands of feedbacks (who are dealers) who tend to have slightly lower positive feedback, because they are handling so much stuff that they can't check it all out. However, there are large numbers of sellers with 100% feedback; I think most of them are selling their own stuff which they don't need any more, and many come from smaller towns in the flyover states. The sleazoids with low feedback are often in our wonderful large cities on our oh-so-sophisticated "liberal" coasts.
