I guess that I will have to agree. Though, it's really more about my own preference, and I'd never go so far as to re-grip. I'm not worried about resale, just more internally proud of my stuff. I've waited for years to upgrade from a refurb'd D50, so I somehow doubt the D7000 will have a short enough life in my hands to reap whatever value "mint" might bring on the used market.
Guess it's like that first door ding on my first ever "new" car.
