So I've found a couple new loves, and I think ounce for ounce they are the best deal in glass right now. They're not the newest and greatest, but they were in their time:
AF-S 28-70mm f/2.8D
AF-S 80-200mm f/2.8D
They can be had for less than half, or sometimes MUCH less than half of their modern counterparts. Sharp, rugged and fast. What's not to love?
Ok so no VR and no "weather sealing", but I generally keep out of the rain and I like my monopod.
So...what's your favorite older lens? Is it a good deal on the used market? How does it stand up over time?
