Hi,If you have a few Pentax lenses it might be prudent to stay with the brand, otherwise I would opt for the D7000. It has almost twice the ISO range and more than 3 times as many focusing points, and scored 92% in the WDC test. I have a D300 which is over 3 years old now and it's just terrific, never posed a problem, gives great pics and I' ll stay with Nikon for life. All the best, Mike.
