New up to 70mm lens advice

[allanm]

I am looking for a new f2.8 lens in the range 17-70mm for my D300. I cant afford the Nikon as I just bought a new 70-200VR . I was wondering if anyone had experience of the other contenders, Tamron and Sigma.
I`ve never used Tamron but believe their 28-75 f2.8 is supposed to be good and sharp.
Any recommendations?

What about a Tamron 17-50? You'll not miss the 20mm....

I've got one on my A200 and it's great. Very quick AF, great built quality and very sharp. Some really good reviews around if you google.
