The one that caught my eye was a 300mm f2.8 (last gen) for about $3200. Sure you'd have to adapt it with a mirrorless or use a D-Series camera, but that is an amazing price for a fast telephoto lens.
Got my ZR this morning. That was some really fast shipping after I ordered it yesterday. It looks brand new. The clock and date needed setup like brand new. Light weight. Small form factor. I Like the 4-inch screen. And the rocker switch by the shutter button to punch in.
