...the Nikkor 28 ~ 105 F 3.5 ~ 4.5. Retailing for about $600. I used to own one and loved it . Pretty good pictures all round but only draw back is you'll lose out on the 28mm if you use it on the D70 (but gain on the 105!) due to the 1.5X magnification factor for digital.
If you seldom use 28mm then it's ok I suppose but that's a good lens to fit your budget.
BTW, I sold it because I need the 28mm for my D70 but ...still have a soft spot for that lens. We had good times together.
Hope it helps.
