That's a great looking set, Doug; very good picture, also, on the station you had it tuned to when you snapped the picture.
It will make a very nice addition to your new home.
If you're looking for a replacement for the remote, I'd look on eBay -- the one-button SC-100 remotes show up there every now and then. Do a search for "Zenith SC-100" and I'll bet a few will turn up. These sets are not rare, so you are bound to find a remote for yours if you keep your eyes open. I'll look there myself, just out of sheer curiosity (I don't have an SC100), after I post this.
Good luck. Your SC-100 should serve you well for many years to come. Zenith was still an American TV manufacturer when these sets were new, so you won't have to worry about quality or being able to find parts for it.
