where I might start looking for a good price. What about used or refurbed lenses? Pros/cons/forget it?
I'm a Canon guy, so I can't comment on the Nikkor lenses, but for used lenses and equipment, I've been doing business with KEH Camera ( www.keh.com ) for over 20 years now and have yet to be disappointed. They rate their stuff very well and they really do stand behind it.
