Okay, y'all had a day to talk me out of this and (thankfully) failed. I placed a pre-order for the D7100 with B&H today!
As much as I would love to think of myself as a first class photographer after more than 45 years behind the lens, the reality is this is just a hobby and a D400 or D800 would be well beyond my needs. I prefer a smaller, lighter weight body in APS-C format for my shooting style, so the D7100 fits me perfectly.
Thanks for all of your input and please carry on!!
