As someone who has and uses Nikon cameras in only the F and F2 era, I am also someone with an interest in what you and your relative will have available. I also look forward to seeing your Available Equipment List when it comes out.
NAS is truly a difficult thing to overcome, although there can be a tolerance build-up over time. Or, it may be just that you finally actually do get just about everything that you truly want. I am not sure which.
