all depends on what you are using it for
You can take great pictures with anything from a $7000 pro SLR to an iPhone. All depends on what you are shooting and what you to use it for. The most important thing (equipment wise)is your lens/lenses quality. Many professionals still use manual lenses produced decades ago. For the price of a 3100/3200, you can probably get a used D7000, or canon equivalent. Check out a photo website such as 500px.com to see what other's are using for similar things that you want to use it for.
Or just get what you want and can afford. The worst camera is the one you left at home.
I'm looking to finally pick up a good camera and not the cheap 100 dollar Walmart special. From what I've read the Nikon d3100 is a go to camera, everything thing you need.
Bt I'm new to all this. No idea what I'm looking for, just want a great camera to take great pictures and something that'll last for years of useable. Can you help guide me?
