Thanks all for the suggestions/comments. I have to say the pics look much better on my monitor at home than on DPR.
Dinahsh3, I wouldn't call the difference huge between the D5100 and the D600, as far as image quality, but it's defintely there,especially at higher ISO's. My primary reason for upgrading was I wanted more manual controls than the D5100 provided. I was considering the D7000 but wanted a little more "bang" for the upgrade, since it shared the same sensor. So when the D600 came out with similar controls to the D7000 along with a great sensor, I thought it was the perfect fit for me. No regrets and I think I'll enjoy this camera for years to come.
