I have one and really like it. It's a great camera with great image quality, however I'm replacing mine with a D810. The only reasons for replacing it are:
1.) My other body is a D500. The D750 is a great camera body, but next to a pro body like the D500 it's control layout just doesn't keep up in fast pace shooting scenarios. The D500/D8xx series cameras have a far better button layout, build quality, and are just generally more user friendly. For a hobbyist this isn't a big deal; but as someone who shoots sports/event coverage it's a deal breaker
2.) More resolution. I'm not huge into chasing megapixels, but I do shoot and print a fair amount of landscape work so the extra resolution will be appreciated by me.
That's it. If you're happy with 24 megapixels and you've never shot with a true professional body, then the D750 is a true workhorse and you'll love it. I wouldn't hesitate to get one based on the recall issues; if you have a problem Nikon will fix or replace it and you'll end up with a new or like new camera body.
