I bought the D5100 first, and if I had to do it all again, I would have read up more, and just bought the D7100 or a full frame camera. Sure, I learned the basics with the D5100, but I could have just as easily learned the basics with the D7100, and saved myself some money. That money could have been spent on one of the Nikon's Trinity of lenses that I'd love to have right now, but can't afford at the moment. My advice is to skip that "intro" phase of learning on a beginners camera (and worry about trying to sell it later) and save that gold for some good glass with a great camera body to back it up. Now Nikon would prefer you bought something like the D3200 and THEN a year later drop some more cash on a D7100. Not only that, but you're going to have to buy a Nikon flash unit. I bought the SB-910 so I'm all set for the rest of my hobby days for shooting with Nikon. Hope this helps your decision making.
