D70, D60... I think it's inevitable to add that I still use my D50 with a 20 years old 28-105mm f/3.5-4.5D that I bought second-hand on eBay. While I agree that "the best camera in the world is the one that you have with you right now" and nowadays we always have our phones, I encourage people who enjoy taking pictures in their phones to try a second hand camera with a good lens.

Seriously, even a beat-up one from eBay, just try! Costs way less than a new flagship phone and the difference is still amazing. And nowadays it's not difficult at all to learn how to use them decently, don't be afraid!
