That all makes sense Scott... When I started out in September of 2012.. I did not even know how well I was gonna like it or how active I would be. I had not done any serious photography since the late 70's and for the last bunch of years, digital P&S. I did want to "over" spend and then not use it (or the features I spent for) so after a couple months of research, I pulled the plug on my D5100.
I do not regret it either... I do lust a little after a 7000 (and did when I bought the 5100) but at that time, I could not justify the cost difference... Now, well a monster has been created, I am wanting to learn more everyday... I shoot lots of photos of various types..... and now am looking at possibly a macro and and a ultra wide (18-55) is my widest.
Will I ever go FX, not likely at my age... but someday maybe an upgraded DX... In the meantime, I am pleased with my shots, I believe I have improved since I got started in September, and there is still much more room to improve and learn with my current DX equipment!
Most important, I am having FUN!

ps: if I had one regret, its that I did not do this 10 years ago!
