I may actually be selling that nikon lens in mm in the next few days. Keep your eyes out for it
It's the D3100
Well in Currys the Nikon 70-300mm was around £350
I heard Tamron can work with Nikon?
I can say that the Nikon 70-300 VR gives professional performance up to 220mm or so, and very good to 300mm if you can stop down a little.
Tamron AF 70-300mm F4-5.6 Di LD Macro 1:2 Nikon+Motor
£99.95

The more expensive APO is at least usable, the non APO version .. stay well away
