You could have another? Kind of a "tool for the job" sort of thing.
It's not that it's an SLR as much as the Topcon opens up the ability for you to use a different, unique stable of lenses.
I have many cameras, all can be used for general photography, but I use each for specific tasks.
Nikon FA when on walkabout in the city on a sunny day with a wide angle. The meter is fantastic in rapidly changing light.
Nikon F2 when I want to use my fastest and heaviest lenses. I use it for birding, general photography, self defense, and canoe anchor.
Pentax MX with 50/1.4 I use as a general carry camera just to have with. It's almost as small as a screwmount rangefinder.
Leotax T2L with collapsible 50mm f/3.5 Hexar for very lightweight carry everywhere camera.
Nikonos V for intentionally shooting in storms or just carrying literally anywhere.
Nikonos III for the same.
Leica M4 is mostly retired and should get a CLA but it's currently loaded with a roll of Pan F 50, to exploit the unique drawing ability of the 5cm f/2 Super Rokkor.
Konica T3 and T4 give me access to a small collection of Konica AR Hexanons which are amazing.
Tools for the job.
In a nutshell, you can either keep the Topcon to have as a shelf queen, keep it to use it, or get rid of it. Sounds like you don't want it, so then sell it to someone who will use it. Simple as that.
