I understand you there, I've been meaning to update my camera for sometime but the cost just always seems prohibitive. My older one still work fine, but they lack features of the newer generation. Just buying the body is expensive, but worth it if you get what you want. Then add in the cost of the lenses you want on top of that... It gets expensive really fast! Your dad sure had some nice equipment back in the day, the good old days of film and the dark room. I've spent time in dark rooms developing monochrome back in the day, it was a lot fun. The day of those chemicals is long gone unless you are one of the few who still insist on using film which is getting harder and harder to find and process!
As for Hive taking out some HBD won't kill your K/E all that much considering how much HP you have amassed over the years. If you're picking up something special for yourself, why not? Everyone should treat themselves sometimes. I hope Hive stays alive and doesn't go to zero, but time will tell. I know some who are jumping ship, and it's hard to blame them. As for me, I enjoy spending time on Hive and won't be pulling up stakes any time soon!
It will be interesting what you decide to do on the camera, let me know. I'll be curious!
