I understand, issues can happen with these projectors. Don't even get me started on Epson though, that is the least reliable, but sure even an Epson can run perfectly. However, people putting high hours on Epsons are much more likely to have more serious issues than a DI problem, like dust blobs or total power failure. The dust blobs can be fixed if someone doesn't mind taking the projector apart, but it's a lot of work.
I'm not trying to be anti-NX or anything, it's just his specific case, I'm trying to give honest advice in here rather than just tell people the latest and greatest. It would help if I had the NX to compare myself, but I don't, but I have compared the attribute differences and I know that sharpness isn't important at his seating distance.
120" at 12', then 4k just barely becomes visible but borderline, and that is only with Native 4k. Pseudo 4k or upscaled, you need to be about 10' compared to the average bluray on 120" screen to see a difference, 8' is where the difference starts getting BIG.
If he's not going for absolute highest contrast above all else, than NX-5 or NX-7 makes sense I suppose, if he wants to spend the extra money.
