Thanks for all the comments everyone. I reckon I'll be keeping this one and running a role of film through it at some point soon.
It's a heavy lump of metal though. I can't see myself carrying it around on a regular basis.
The cure for that is to get an 8x10 view camera, and go hiking with it. After several long hikes with the 8x10, tripod, some filmholders, a lens or two, some other accessories, lunch, and etcetera, carrying that tiny featherweight 35mm won't bother you a bit.
The Topcons were/are great cameras and deserve more recognition than they get.
