I am also in my late 60's and have had scanners since I was a kid.
I got the 100 about a month ago and have no regrets. The portability is what sold me, and since I am in the NY/NJ area there is always plenty to listen to. If my wife is in the living room and I am in the shed or my man cave I can just pick it up and take it with me, as she is not always a big fan, although never really complains about it. A 200 would be nice, but it would be based in one room, but perhaps one day!
With COVID I have been commuting to the office in NYC by car, most times spending more than an hour each way, and so I just place it in the cup holder and get great reception in both states with my Remontrix antenna. I also have the 100 in a leather case bought from Scanner Master, which seems to provide great protection. Setting up the favorite lists was key, and I have to turn the car radio lower than I normally like to listen to it, but all in all, I am very satisfied. Perhaps one day soon I will treat myself to an installed external speaker in my Explorer.
So far, I am very satisfied with the Uniden technology and hope to get many years of listening pleasure!! I hope you all enjoy as well, and thanks to all for the sage and practical advice which was so helpful in getting me started with setting up & programming the 100 and using the Sentinel software !
