I also was shooting a D90 with a D80 as backup. I sold my 105vr to help finance my D7000. Best decision that I made. My kids now us the D80 and my D90 is my backup. I believe you need medium to pro glass to get the benefit out of the D7000. If you're on the low end of Nikon or third party glass, you may want to stay with the D90, and spend the money on better glass. If you have the good glass, go for it, you will not regret it.
