I became too apprehensive about flooding my V, and, so, I decided many years back to no longer dive with it. And then I purchased a III (the last all-mechanical Nikonos) a couple of years ago, which I use now with the 15 and SB105 I used to use with my V.
My only issue now pertains to losing access to the university darkroom I used to use. It was shuttered a few years ago. My house is incredibly dusty, so developing slides and film at home doesn't work so well.
I haven't been able to find a film drying cabinet to purchase, but I read recently about making a 35mm film drying "cabinet" using PVC pipe, a couple of HEPA filters, and a small, low voltage, low power fan. Seems neat. I am hoping to find the time to try to make one of these.
