the problem with using anything other than nikon/nikkor is much slower AF action and it sounds like you need to be pretty quick to get the right shot.
i have the Tamron2.8f 28-70 (and it is super nice glass but slower to focus especially in low light..), also i have the nikon 2.8 70-200VR, the nikon 18-200VR and a few other..
also buying nikon means you get top notch service if you ever need to get the lens cleaned or serviced..
by upgrading from your d60 you also get better and faster AF..
