The 80-200 I picked up was also an f/2.8. The 80-400 is an f4.5-f5.6 with VR. The only thing I don't like about the f2.8 is it has rounded blades so no flares, and no VR. I shoot most everything at night, completely night, outside. So without VR it's harder to get some things and I just hate using a tripod, it limits angles. Either way, I grabbed them both for under $800 combined. I want the newest of that family the f2.8 70-200 with 4 focus locks so bad, but really, there isn't much of a difference between it and the 80-200 besides having gen3 VR, I can't drop $3k for just VR.
Plus, I really prefer the 400mm range because I shoot at long distances, but the AF-D 80-400 is the slowest AF Nikon lens ever made and at night using manual focus outside of Live View (blech) is almost impossible because there is no focus film in the bodies over the mirror anymore.
The lens I'm really on the hunt for is the f2 105mm DC. That thing is amazing.
I'd also like to pick up a couple things like whatever the focal range is in f2.8 something like 14-70... Can't remember without getting on Rockwell's site or being in the camera shop. And a couple wide and ultra wide lenses. Like a prime 16mm and a prime 10mm. I really need to upgrade my 35mm to the pro glass one. It was the first lens I bought and I really like it, I didn't see the difference at the time from the 1.8 to the 1.4 for a $600-700 price difference and the weight. But after a year of using what I have, the $1000 version of the 1.4 lens is really where I should have gone to begin with. It's really to bad they don't have something as good as the nifty fifty in 35mm. But oh well.
I don't expect that I'll be finding the stuff that I want/need now as easily for cheap prices. But that's really because the 80-200 and 80-400 lenses are so widely available used. The Macro's, the 35mm's, and the f2 DC lenses are specialty and you won't see people that have a bunch of money who bought one and now are dis-investing in them. They're pretty much only picked up by pros and when they are up for sale, they are thrashed.
I could do a refurbishes. But refurbished is almost the same price as new, without a real warranty and depending on who refurbished it, may not be worth the time it takes to mount the lens. But I'm sure you're very aware if you shoot with quality lenses yourself my trepidation on refurbished stuff.
