Hey guys Need some advice... I have a Nikon D40 right now, and I have an opportunity to get a d80 body for $400. I was wondering if this would be a good deal/upgrade from my d40. I plan on selling the D40 and an 18-55mm nonVR Lens on ebay and I figure I can get around $300 for it. So essentially it would be $100 for the upgrade. Is it worth it guys? And is it a nice deal?
