I used to have a Nikon fit version. It's a good lens although getting a good one appears to be a bit of an issue. I used it on FX and DX and got some decent results. If you are going to get one make sure you give it a good testing as there seems to be over the average amount of bad copies around with a lot of people having issues with sharpness at f/2.8. Everyone I know that has had one says it is razor sharp at f/4 but you buy these lenses really to use at f/2.8.
The copy I had was sharp at f/2.8 but a friend lent me his Nikon VR2 for a week and I just had to have one.

I found the Nikon to be a lot quicker to a.f especially in poor light. As for the O.S I personally had some issues with mine although I have not heard of many others saying the same so it could be that there was an issue with my copy.
If you want a lens in this range that won't break the bank these are very good value for money. That said however, I am sorry I just didn't hang of until I had the cash and get the VR2 at the time because I am absolutely delighted with it. It cost me an extra £700 to upgrade to the VR2 and I have never regretted it.
Used Nikon VR1's pop up on the classifieds here all the time at decent money as another option.
