I love my 300, it was an unexpected anniversary gift a couple years ago...now I have to teach my husband about good "glass" Cait bought her 7000 with the money she got from college graduation gifts (and what was left of her scholarship funds ) It has a few toys that the more "professional" 300 doesn't have like auto focus using live view would sure love to have that!!
I noticed that you had a D300s,very nice and very fast too ..and drooled over her D7000 ..
I still use my D60 as a backup body with the 18-55 kit lens,with my 70-300 on the D90,its more to carry certainly,but its let me get shots i would have missed without it..it would be much easier with 2 D90 bodies,and the way the prices are faling,as they are effectivly discontinued,that may happen this year(unless the D7100 causes a big drop in D7000 prices then who knows ,
yeah, I've got a nikon D300s as my primary body, while my daughter has a new D7000...we've got two D100's now not being used but they are so "primitive" that I don't think about taking one with me along with the "main" bodies (I'd need a bigger bag that's for sure ) but I just might start doing that when I know there'll be multiple possibilities...
