First, blurry has to do with using too slow a shutter speed, not the lens
I shoot using a 400 mm f/2.8, but that would break most anyones bank.
Go into a camera store and see if you can find a good used 70-300 mm ED lens. They have an aperture ring so you can use it on almost any Nikon camera ever made. I use mine on an old F4 when shooting film.
